Episode Title:
A Room of One's Own / Carts and Crafts
Episode Description:
A Room of One's Own: After another dispute with Simon, Alvin convinces Dave to give him his own room after a test of maturity which he successfully passes. Alvin then moves to the only spare room in the house - the basement. However, the Chipettes soon realize that the Chipmunks are unhappy and miss each other, so Brittany hints at Alvin that if he reverts to immaturity, Dave will probably move him back into their common room. Alvin applies the plan immediately and is happy to get back with his brothers, and although they do sort of apologize to each other, the dispute soon resumes...
Carts and Crafts: Alvin leaves Theodore's bike in the rain, so it gets rusty and soon disintegrates. Looking to offer Theodore a new bike, the Chipmunks participate into a competition consisting in rounding up shopping carts left all around town and bringing them back to the supermarket. The episode then turns into a parody of Western movies with the school bully, Derek Smalls, stealing their "herd" of carts before being chased away with help from Ms. Croner. Unfortunately, it is finally revealed that they only won a tiny bike statuette.
