When Cosmo is expelled from the house because of being an annoyance to everyone, and he suddenly turns into a superhero after he is seen flying and saving Poof by the citizens of Dimmsdale.

Timmy meets his grandparents, Grandpa Vlad and Grandma Gladys, who host a long and disgusting Yak-filled holiday at his house called "Yaksgiving". After a week of torment, Timmy foolishly wishes they never came to America--but then he finds himself back in Ustinkistan, his grandparents' native country, with no money or useful magic (every time he makes a wish, he receives turnips instead) to get back home.
