At Pumpkins County Middle School weird things happen every class period, not to mention during lunch, but nobody ever makes a fuss. Principal Garish thinks what's weird and...well...creepy is how fascinating the mysterious goings-on are to Carol, a big-city girl new to Pumpkins County, who finds kindred spirits in Mitchell (monster expert), Mark (military brat with logistics know-how), and Rosario (girly girl on the outside, muscle underneath). The Creeps are on the case to figure out the spooky mysteries and still get to class on time. Last week it was a pudding monster. This week, it's disappearing classmates and a suspiciously coincidental animal-rights petition being passed around by the snootiest girl in class. Could she be behind an amphibian menace? Or could it be the mad genius who lives in the sewers? How about the school janitor? The Creeps will track down the answers!
