The Kids Next Door set off on a mission to the ice cream factory.

It is a sad day in the treehouse, when Chubbo, one of the KND's power-providing hamsters passes away; and it is saddest for the overly sensitive Numbuh 3, who even maintains a vigil at his grave until the weather proves inclement. But unwise is the one who mourns too long for the dead, because during the dark and stormy night, a gang of ghostly hamster arrive, and drag the terrified Three to the hamster afterlife! Now the team must penetrate the very netherworld to rescue their friend, but can even the KND overcome a mob of restless rodents?!

The team is giving a report on their mission to retrieve a mysterious box, while trying to keep the Delightful Children from getting it. Unfortunately, each operative's version of the story is... exaggerated to say the least. Can their superiors find any truth in their speculative snafu?

When Numbuh 1 is fishing with his dad, Numbuh 86 and her group appear and tell him that he's been scheduled for a decommissioning! Although he escapes, his teammates are taken to be decommissioned, so he has to enlist the help of Numbuh 2's little brother Tommy to try and save them! Unfortunatly, he is too late, but can he still save the Moon Base from a fiery demise?

The true history of the genesis of the Adult-Child conflict is revealed. This is the story the Adults do not want you to hear.

Hoagie and the gang go to the KND Academy to watch his brother Tommy graduate while Father plans an all-out attack.

Numbuh 4's disgust at anything Rainbow Monkey only increases when he finds himself trapped on Rainbow Island.

Numbuh 4 accidentally eats a brussels sprout, sending the rest of the KND on an emergency Fantastic Voyage to stop the dreaded vegetable from being digested.
