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 escape and take over the planet? 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 laugh-out-loud adventure that sneaks in factoids and comics at each chapter's end.
