Psycho Sticker

Psycho Sticker first appears in Book 3 as a massive, quilled ogre-hedgehog hybrid that dominates the train-car battlefield, serving as a formidable mid-tier boss. Its presence marks a turning point in Carl and Donut’s dungeon progression, forcing the party to adapt tactics against heavily armored, area-denial enemies. Across later books, Psycho Sticker’s design influences subsequent monster generations, with its quill-shooting and crowd-control abilities echoed in higher-level variants, cementing its legacy as an archetype for tanky, spiky bruisers in the Crawl.
