While visiting HorrorLand, Marco Gonzales and his friend Gabriella Smith find a rare edition of the The Wizard of Ooze at Jonathan Chiller's HorrorLand shop. The Ooze is a popular graphic novel series about an evil mutant who is made of oil sludge. Marco is excited because in the back of the comic are secret instructions on how to gain your own super powers. Unfortunately, after mentioning the special edition at a comic convention, a couple of unsavory characters want the book, including a guy dressed in an Ooze costume. Marco could really use those super powers right about now!
