In the sequel to "The Bloo Superdude and the Magic Potato of Power", our hero (Bloo) must set out on a quest if he wishes to attend a ceremony honoring The Great Creator of Everything (Mac). In reality, Bloo is sick and hallucinating, making him think he's the Superdude when he's only running around the house. A delirious Bloo tries to get out of the house to get to Mac's birthday party outside.

A little dare between Mac and Bloo turns into a huge daring competition between the house members once Madame Foster gets involved.

Bloo is sad about Eduardo getting adopted and holds auditions to get an alternate one; meanwhile, the residents get letters from those that were adopted in another Adopt-a-Thought Saturday.

The series finale. When Herriman tells Bloo that Mac is moving, Bloo decides to give him the best day ever, though things do not go as he plans. All day, Mac does things with everyone but Bloo, making him angrier after every disappointment. However to everyone's surprise/relief (and Mr. Herriman realizes he forgot to mention this), it turns out Mac is moving to an apartment (the one next door) that was held by Louise's family, and with Cheese unable to follow her because her new home doesn't allow imaginary friends, he moves into Foster's. This was Craig McCracken's final project before he quit his job at Cartoon Network.
