The monsters take the Toxicity Challenge as the first event in the Scare Games, attempting to dodge as many Stinging Glow Urchins as possible. Representing human children, these can make body parts swell up gigantically, and Squishy's whole body swells up when he gets a Glow Urchin thrown into his mouth.
