Episode Title:
A Room of One's Own.
Episode Description:
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 back 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...
