When Nature Shrieks is an episode of Monsters vs. Aliens. It aired on June 29, 2013.


There are a few sights that make both the Monsters and Aliens uneasy, one of these is General Monger's smile. His reason to smile is his annual camping trip, so stoked is he that he grants both teams weekend passes to join him. The only ones to join the General willingly are Sqweep & B.O.B. Susan wishes to back out with Dr. C., The Missing Link & Coverton, but Monger denies her that liberty: He haunts her with the memory of her brief stint as a Butterfly Girl, so she's obligated to join the trip. Monger thinks the trip will be to his liking, but Sqweep wishes to use the trip for her studies, bringing with her a tent filled with her gadgets. After one too many luxuries and B.O.B. eating his map and compass, Monger has had enough and sets up his own fire. But following a storm that fries Sqweep's tech and Monger breaking his ankle, it's up to Susan to save the trip.


  • Dr.Cockroach: "I'm afraid I'm going to have to pass."
  • Missing Link: I'm out Too
  • Coverton: And I'm allergic to things I despise.
