Timmy wishes for magical "youdoo" (voodoo) dolls to control his enemies, friends, and family, but he runs into really big problems when Tootie finds a You Doo doll of him that Cosmo erroneously left lying around. Things get worse when Francis takes it away unlawfully from Tootie without asking her permission, but Timmy manages to recover the limbs of the dolls of his fairies, put them back together and wish him and everyone back to normal.
