A Goosebumps 'Choose Your Own Horror' Adventure! This Halloween you're stuck with a lame costume called "vampire in a can": a cheesy vampire costume stuffed inside a can. But then you finds a strange packet of red goo inside that will turn anyone who swallows it into a vampire. Will you swallow it and turn that lame costume into the real thing? Or will your adorable poodle Fifi wind up with a bite that's worse than her bark?
