  • Monster mash-up: after each answer, the team that solved it adds one feature of that monster (an eye, a horn, snakes for hair) to a shared drawing. By the end you have one very strange monster.
  • Myth-busters: for the medium riddles, ask players to say where the monster comes from (Greece, Japan, Scotland, North America) for a bonus point.
  • Monster under the bed: hide riddles on slips of paper around the room. Each player finds one, reads it aloud, and the others guess.
