Game Overview

Remember that weirdly charming Nickelodeon cartoon about monster kids learning to scare humans? This Genesis game nails that vibe perfectly. You play as Ickis, Oblina, or Krumm—each with their own ridiculous moves—bouncing through levels that feel ripped straight from the show. Ickis can stretch his ears to swing across gaps, Krumm throws his own eyeballs (gross but useful), and Oblina slinks through tight spaces like living ink.

The levels are these wonderfully gross playgrounds—haunted mansions with jump-scare portraits, sewer pipes dripping who-knows-what, even a junkyard where everything looks like it might bite you. The controls take a minute to get used to (Krumm’s floaty jumps still mess me up sometimes), but once you get the hang of each monster’s quirks, it’s surprisingly satisfying to scare the pants off pixelated humans. The soundtrack’s full of that creepy-cute carnival energy the show had, too.

It’s not the hardest platformer out there, but that’s kind of the point—it’s more about goofing around in this bizarre little monster world. If you ever watched the cartoon after school, this’ll hit you right in the nostalgia.
