  57. ward-eyes on sticks. can be eaten, but then they see inside you
  58. thomas tank engine faces in dungeon walls, offer to swallow you, there is treasure + problems in their gullet, compete for your attention, nearby engraving says only one lies, too much competing information

  76. grass, and then vines, it’s an underground jungle!  panther attack! monkeys steal your stuff! probably a gold mine, w/r/t calories. but watch out for the idol… if you need an excuse, why it’s underground, it’s all pale, although very humid.
