After Chowder eats a group of hot peppers in order to keep them from escaping the kitchen and burn down the city, he begins to breathe fire whenever he opens his mouth, whether he wants to or not. Quickly becoming an incovenience to Mung Daal and the others, he runs away to go live with dragons.

Against Mung Daal's wishes, Chowder secretly starts his own catering company for a bunch of trash-dwelling vermin. However, when these vermin attempt to kill Mung, Shnitzel and Truffles, Chowder must choose between his friends and his dreams.

Truffles tries to impress the members of The Big Hat Biddies, and the others try to help by making a big feast for the club.

Shnitzel tires of his adult responsibilities and decides to act like a child, much to Mung Daal's chagrin. Forcing Shnitzel's responsibilities on Chowder, Chowder then decides to act like a baby and Shnitzel follows suit: forcing Mung to send them to the baby pound.

Mung (and eventually everyone in town) blackmails Ms. Endive with an embarrassing picture to gain access to her pool.

After Truffles makes the plants grow with her voice, Chowder becomes her apprentice. But that leaves Mung heartbroken and now he'll do anything to win Chowder back.

When Chowder and Schnitzel make a delivery to the Asian section of Marzipan City, Schnitzel is confronted by his mysterious past and his greatest shame. Chowder must help Schnitzel rectify this problem in order to reclaim Schnitzel's honor.

A chicken ghost takes over Chowder's body, causing problems for the gang.

Chowder accidentally eat a tootin' fruit and becomes a musical sensation, but his life is taken over by his agent, Gorgonzola, and soon he misses Mung and has to go back with him.

Twenty years in the future, Chowder still has refused to grow up. He must accept the responsibility of training his own apprentice or everyone he loves will be unable to move on with their lives.
