Goosebumps Horrorland: The Wizard of Ooze (Book 17) by R.L. Stine

At a comic book convention, Marco Gonzales and his friend Gabriella Smith head right to The Wizard of Ooze comic booth. Marco is a huge fan of the Ooze, an evil sludge mutant who can turn people into ooze by touching them. He was given a rare edition of the comic at Jonathan Chiller's HorrorLand gift shop. But this special edition attracts all kinds of unwanted attention. Even the Ooze himself seems to be after it. But how can that be? The Ooze is just a comic book character... isn't he? 142 pages Scholastic (Oct. 1 2010)
