Pustossers (or Tumor Pustossers) are Mimics found in the Steamport City area, and in certain sections of the Hatchwood Wilds. Their grayish brown, furry bodies are covered with large purple tumors, which the creature then rips off to throw at the player. Upon death, the Pustosser shoots out 3 more tumors upwards. According to Cypress, his tumors have the same surface of the haze generating fungi.
