Babs and Buster attend a twin convention but are soon ostracized for not being exactly the same. Hamton accidentally becomes famous, and Plucky steps up as his manager. And Sweetie won't let anything stop her from finishing her board game.

When Buster's good luck is replaced with The Unluckys, it causes a chain reaction that could cause Acme Loo to close forever, so it's up to the Toons to find the long lost treasure of a cereal mascot to save their school.
