Granny Yak has a new boyfriend - Chatterbox Ox, but Yakkity is suspicious, and Professor Crazyhair tries to win back Granny's affections.

Yakkity, seeking some freedom, decides to srike out on his own and move into a nearby treehouse. But when Granny rents out Yakkity's old room he soon becomes suspicious of the new tenant.

Yakkity and Keo fear the worst when Keo's Dad is nowhere to be found. The two search for the missing pineapple only to find themselves with no clues and an entire town full of strangely suspicious residents.

Yakkity becomes jealous when Keo gets a new pet so he decides to order his own pet and what he gets is a snakehead fish that can live outside of water. Yakkity grows close to the fish but Keo warns that the snakehead fish is a wild animal that shouldn't be kept captive.

A soapbox race is announced, and the prize is a year's supply of Professor Crazyhair's Egg Salad. When Lemony forms a team with Keo, Yakkity eventually pairs with a peculiar new neighbour.
