Pixies have bought fairy world! Under the new management of the monotonous and very corporate Pixies, everyone's wishes are being denied. So Timmy challenges the head pixie to a winner-takes-all game of miniature golf: If Timmy wins, the pixies will leave fairy world, but if he loses, Cosmo and Wanda will have to leave Timmy forever.

Timmy is ordered to undergo a program that will teach him to make harmless wishes.
