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.

After Timmy saves Vicky's life after her attempt to torment him backfires, she is shunned by her fellow evil babysitters, and loses all of her friends. After Timmy suggests to her that she try being friendly, Vicky begins to smother Timmy with friendliness, and he must find a way to change her back to her mean self, since she will not let anyone else near him.
