Timmy wishes for "You Doo Dolls", magical doll likenesses of Timmy's teachers and classmates that can control whoever they depict, but he runs into problems when Tootie finds a You Doo doll of him that Cosmo erroneously left lying around, and things get worse when Francis steals it from her! Now Timmy must retrieve the You Doo doll of him before it is too late!
Timmy is being bullied by Francis, so he wishes for a way to get back at him. Cosmo mentions about using a Yoo Doo doll, which as Wanda explains, is a secret doll they never tell kids about, a You Doo doll is similar to a Voo Doo doll, in which whatever you do to the doll happens to the person the doll is of. Timmy used a Francis Yoo Doo doll to get revenge and wished up an entire box of dolls of all his friends and family, however, included in the set was a Timmy doll, which ended up first, in Tootie's hands, then Francis's, which almost kills Timmy when the doll is thrown to a wood chipper (which shaves his head). Timmy manages to wish away the dolls moments before injury, and learns a very valuable lesson: It's wrong to control other people, but (now bald) Timmy instead agrees that boys shouldn't play with dolls and sticks to action figures.
