Glip! Glop! Gloop! What looks like dog vomit, smells like a corpse flower, and stars in one of the scariest movies Stink Moody has ever seen? Is it the Blob? The Glob? Son of Glob? No, it's . . . slime mold! Stink may be a super science geek, but even Dr. Stinkelstein is feeling freaked out about having a slime mold living and growing in his very own room. At Saturday Science Club, Stink learns that these one-celled organisms are smart enough to find their way out of mazes and gang up on food sources -- so who says they aren't smart enough to take over Stink's pets, Stink's room, Stink himself, and . . . the world? Vintage horror flicks meet classic Star Trek episodes as a wary Stink (with some help from Dr. Judy Moody) comes to know and love an unusual new pet in a hilarious adventure that sneaks in factoids and comics at each chapter's end.
