Yakkity decides to add a ventriloquism dummy to his comedy act but it only becomes a hit when a nasty worm inhabits the puppet and starts doing the talking.

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.

In order to keep from losing his position as one of Mr. Trilo's clients, Yakkity promises the agent that he can organize a huge entertainment event called Yakstravaganza. And to pull it all off Yakkity seeks the help of former entertainment legend Keo's Dad.

Yakkity is embarassed by a new hat that Granny made for him but eventually the hat becomes a popular fashion trend and Yakkity is credited as the creator. When the hat frenzy dies down Yakkity partners up with Keo and Mr. Highpants so that they can come up with the next fashion trend that will make them rich.

Yakkity and Keo come up with their very own sport and name it Yakeo which becomes popular with everyone except football jock Rondo.
