Mr. M tells of a story in which his munching mouth (which is how he gets his sound) got him into trouble at the market. Later Sam Gump puts Mr. M to the test: Can he recognize words that start with his sound?

Mr. T retells the time he talked his way out of a confrontation with a bully called Terrible Tough Tony. It seems tall tales accompany Mr. T's tall teeth (which is how he gets his sound) wherever he goes.

Mr. F can't find the right shoes to go with his funny feet (which is how he gets his sound).

Mr. H is afraid of the barber shop. He thinks haircuts hurt. That is why Mr. H has that horrible hair (where he gets his sound).

Mr. N causes a disturbance during story hour at the library, and helps Nardo the detective tame a Nasty, who turns into a Nice Nasty. Mr. N sings ""Meet Mr. N"". STARRING MR. N, NARDO, THE NASTY, NED THE NEWSMAN, the LIBRARIAN and a NURSE.

Its Mr. B's birthday, and he meets Boris the Bulletin Board (who sounds just like Boris Badenov). The Letter People play party games. Mr. B sings ""Meet Mr. B"" STARRING MR. B, MR. H, MR. F, MR. T, MR. M, MR. N, BORIS THE BULLETIN BOARD, CAPITAL B, LOWER-CASE B, CREEPY BOY PUPPET WITH BIKE, CREEPY GIRL PUPPET WITH BEACHBALL, and CREEPY MAN PUPPET WITH BANJO.

Miss A arrives in town with a deceptive sneeze (hers is the same sound that starts ""A-choo""). She plays a carnival game in which her sound appears in all four parts.

A new television station is starting up in Letter People Land. All sorts of dreams fill the heads of the Letter People, as they try songs, jokes, and juggling. But their truest talent is in their sounds, and how their sounds blend together. There's only one catch: Miss A has to be in all the ""sound catches"" for the time being.

All the Letter People show up at the new TV station to try their sound catches on Monty Swell. For the first time, all six Letter Boys make their sounds catch with Miss A. At Monty's suggestion, another Letter Boy stands on the other side of Miss A, and they make a word. It's the inspiration for a game show called The Catching Game.

Clue A presents Monty Swell with a set of rules for The Catching Game. Each Letter Person can only make a sound when he or she is in a ""clue box."" Of the three clue boxes, the middle box is larger to emphasize Miss A's role (she's the only Letter Girl at this time). The Catching Game then airs for the first time.

Mr. Z dresses in a coat lined with ""zipping zippers,"" which is where he gets his sound. He takes the advice of Zero the Owl to go to Letter People Land, but that means getting through the Zigzag Forest.

A rustic Western setting provides the drama as Mr. P tries to get his food back from the Purple Peek-a-boo Palookas.

Mr. S is a superhero residing in a secret sock cave. He needs to find the starter for his car, the Sockmobile, to drive his friend Slaw to the studios of The Catching Game. Trouble is, the starter must be recovered.

Miss E drops in (literally) to Mr. Z's apartment. It's apparent that Miss E is the strongest of the Letter Girls, since her sound comes from the same sound that starts ""exercise."" She cleans up Mr. Z's apartment before making her debut on The Catching Game.

Nardo the Detective returns. This time, he needs Miss I to help catch Ingrid, the pilferer of indigo ink. Miss I is the perfect right-hand Letter Girl for the job, as her skin is irritated with the mere mention of a word that starts like ""itchy itch.""

Miss O is the most obstinate Letter Person around, and that's where she gets her sound. She stubbornly refuses to alter her strange opera about an ostrich and an omelet. Along the way, all the existing short sounds are reviewed (not surprisingly, Miss A, Miss E, and Miss I have unsatisfying roles in Miss O's opera). The abrupt end is not the end, as Miss O introduces a story about an odd octopus.

Just what are the Unforgettable Underground Uglies? Miss U's uncle believes they took his baseball. But the Uglies want more from Miss U, whose sound is the same sound that starts ""upsey-daisy umbrella.""

A vandal has defaced Mr. V's violin and other objects that start with the same sound that starts ""violet velvet vest."" Both Mr. V and Mr. B plot strategy when the vandal makes a bold claim.

Mr. L is ready to open up a lemonade stand on the beach, but he'll have to contend with two villains first.

Mr. B, Mr. P, and Mr. Z try to add their trademark clothing items to Mr. V, tearing his favorite vest in the process. In an act of vanity, Mr. V says he will never end a word so that no one will see the tear on the left side of his vest. That doesn't stop the other Letter Boys. They clutter their add-ons to Mr. S's super socks. Not all of them will come off, though. Mr. Z grants Mr. S the right to use the ""zipping zippers"" sound sometimes.

Mr. V goes to the set of The Catching Game to explain his restriction (see Episode 20) to Monty Swell. He and other Letter People try to make the word ""vest,"" which is not easy to do in a clue box built for one. Mr. S and Mr. T are forced to share the ending clue box to make the word. Once that's done, Miss E declares that the combination of consecutive Letter Boys fit into a ""Squoosh Box.""

Dolly the Dragon has escaped from her lair. Her owners get help from Mr. D, whose sound is the same sound that starts ""delicious doughnuts.""

A ghost has rid the corner grocer of all his green grapes. This calls for only one man: the newly-arrived Mr. G. His sound is the same sound that starts ""gooey gum,"" which is one of the items they offer to the ghost as a trade.

A carnival passes through town, filled with everything starting with the same sound that starts ""cotton candy."" A camel named Claude is part of the retinue, as is Mr. C, who is in search of his big break in show biz.

The Grand Shish of Kebab asks Mr. K to rescue the nation's King, an expert kazoo player, from the clutches of a kazoo detractor. Mr. K, donned in leather football gear, heads off amidst a storm brewing in Letter People Land. Mr. C knows something about Mr. K's sound: it's the same sound that starts ""kicking.""

All the other Letter People discover what Mr. C knew all along: he and Mr. K have the same sound. Both of them go to Miss I's Itsy Witsy Ice Cream Club where, grudgingly, they try to settle their quandaries. Which Letter Girls will each stand next to? And is squooshing with Mr. K safe?

Mr. W needs to get back his wonderful wink (which is how he gets his sound). An impatient man unknowingly helps Mr. W get his wink back.

The Letter Girls know well that they have to appear in every word that Letter People make. Miss A suggests that each of them adopt new sounds to go with their names. Before they know what hits them, the Green Gorillas band asks the Letter Girls for help to keep up their popularity. At that moment, Miss E is coaxed to write a song about the Letter Girls' long sounds. First with the news is Frantic Freddy, rambling wreck of the record rack.

With each Letter Girl now bearing two sounds, how will people know which sound she is using? This question hovers over the planned melodrama. Quickly, the Letter People devise new rules: (A) a Letter Girl can use her short sound if the Letter Boy is alone at the end of a word (holding the badge of Cooperation), and (B) Miss E can stand outside the Ending Clue Box as a signal that the Letter Girl in the Catching Clue Box is using her long sound.

Nardo the Detective gets an urgent message from millionaire heir Poopsie. It seems Poopsie can't read a note that begins, ""Come to the B-O-A-T."" In a meeting at Nardo's office, Miss O proposes one of the Letter Girls (the first) should say her long sound while the second Letter Girl is silent. Once they decipher Poopsie's first note, a few more notes await.

Nardo the Detective has become a night watchman at The Letter People Hall of Fame. Walking through the halls and seeing displays of the Letter Girls, brings back wonderful memories of sounds and sound catches.

Nardo observes the displays honoring Mr. T and Mr. N, among other Letter Boys. He hints to the events of Episode 20, involving Mr. V's torn violet velvet vest. If it weren't for the word ""vest,"" who knows when the Divided Catching Clue Box would have been needed?

Nardo retells the stories of Mr. C and Mr. K, their separate arrivals, their identical sound, and their eventual ""agreement"" of who stands before what vowel.

Nardo provides flashbacks of all the Letter Girls' uses of long sounds. This includes the Cooperation rule from Episode 29.

Newcomer Mr. Y is putting everyone to sleep with his yawning. Sure, it's how he gets his sound, but he and some other Letter People are needed. There's a creature up in the mountains called the yodel, just the perfect guest for Letter People Land's upcoming Outdoor Sound Festival.

Before their outdoor Sound Festival, the Letter People split into factions over the tiring Mr. Y. Miss I intends to give Mr. Y her sound so that he can appear in the middle or end of words. This becomes the focal point of the Sound Festival.

Officer Jabberwocky informs Mr. J he must clear out his jumbled junk—which is how Mr. J gets his sound.

The Genius Gem is missing from the museum. It ends up in Mr. J's junkyard. Mr. G touches the gem and disappears. Now Mr. J and Officer Jabberwocky must follow a set of instructions that gives Mr. G the right to use the J sound.

Mr. R has no rip in his ripping rubber bands. Can he trust the repair service of Roscoe and Ringo? Those two renegades are more interested in comedy revue.

For a week—ever since Miss A had disappeared, the Letter People Space Agency has received signals from a faraway planet. Mr. R has been assigned to rescue Miss A. This leads to the most extraordinary discovery. Befriending Lucky Star on the journey to planet Snickers, Mr. R learns of the Divided Catching Clue Box. With it, Miss A and Mr. R produce the AR sound.

Miss A returns to Letter People Land, but not before another spaceship whisks a willing Miss O to the planet Snickers. Together she and Mr. R enter the Divided Catching Clue Box to make the OR sound. But are they a match for the Empress Mung and her guards?

Empress Mung is truly merciless. She has coaxed Miss E, Miss I, and Miss U into one of her spaceships bound for the planet Snickers. Will the Empress get more wondrous sounds out of the Divided Catching Clue Box, or can the Letter Girls and Mr. R fool her?

Nardo provides flashbacks of the adventures surrounding Mr. Y, Mr. J, and Mr. R—including the Star Trip trilogy.

Things seem to be going wrong: Mr. B loses his voice, Mr. H's head looks even more horrible, and Miss U's goat is cursed into not bleating. All these things occur when anyone is tagged with a red letter X. It's up to Nardo the Detective to track down the source of these marks. Once he does, he offers to help Mr. X get a sound.

Miss O loses her voice prior to her engagement at the opera house. She and an assemblage of Letter People must go to the laboratory run by Mr. Q. Before Mr. Q can help the Letter People, they must help him acquire a sound.

A professor's Word Machine goes haywire when the letters Miss O feeds it, make unconventional sounds. All these words will not change their sounds for anybody. They will run havoc for the next eight shows.

Mr. C convinces Mr. H to make more than one sound. They agree to make the sound that starts ""chewy cherry,"" but Mr. H holds out for one clause: ""Only if we get into a regular clue box.""

An old theater in Letter People Land has been haunted since 1930 by a creature called ""The Thing."" Turns out The Thing is the only creature, other than a Letter Person, to have sounds.

Mr. H loses a bet and agrees to make a new sound with Mr. W: the same sound that starts ""whistle."" It's a loud sound, prompting Mr. S to ask for quiet. He gets to make a quiet sound with Mr. H.

This final visit to The Letter People Hall of Fame gives flashbacks on the previous six shows. We see pictures of Mr. X and the ever-rare Mr. Q.

Cindy dreams a Cinderella dream of wanting to appear on the set of Frantic Freddy's Rocking, Hopping, Dancing Party. It's an exciting prospect, especially because Freddy introduces the -ING sound. It's a heavy sound, which means that short words with short-vowel sounds must double the single consonant. The highlight of the afternoon is the Letter Girls' performance of a song called The -ING Sound.

Frantic Freddy is trying to stay awake seven full days while working the Rocking, Hopping, Dancing Party. Early on, he tells all the viewers that Silent E vacates whenever -ING appears at the end of words with a long vowel.

Iggy, who we first saw in Episode 15, befriends Chopper, an emerging karate student who breaks words. Through a flashback, we see how it began. Chopper enlisted at the Temple of the Silly Bull to learn how to break words into parts.

Iggy now becomes a student at the Temple of the Silly Bull. He reunites with Chopper to break words into three syllables.

Miss O emits a loud sound when Miss U sticks her with her umbrella. It's the start of an expanding realm for Miss O. She convinces Miss U to join her in the Divided Catching Clue Box to create the OU sound as in ""loud."" Mr. W gets into the act as well, teaming with Miss O for both the OU and long O sounds.

Miss I gets a nasty sunburn at poolside to compound her itchy itch. In the anxiety of the moment, Miss O coaxes her into teaming up for the OI sound, inspired by the word ""boy."" Naturally, Mr. Y can get to work the OI sound as well.

What is in that soup Zelda (the witch from the other side of the Zigzag Forest) made? Whatever it is, it has allowed Miss O to make two new sounds with herself: the long OO in ""school"" and the short OO in ""good.""

A jaunt through a fun house proves awfully scary for Miss A and Miss U. In the process, they agree to make a new sound in the Divided Catching Clue Box. Mr. W is called upon to take Miss U's place in said clue box when the time is right.

What are those strange marks hovering over Letter People Land? Miss U, Mr. S, and Miss O introduce themselves to the three punctuation marks, who instruct how to construct and read sentences.

The seventh game of the World Series pits the Letter People Land Clue Boxes in a jam at Mudville. They are down by three runs in the ninth inning. To compound matters, the fans back home can't get the game action. All they have are transmitted sentences about the final two at-bats.
