Description

CR 0 : DCR 0 - OCR 0

A voracious and chonky green caterpillar-like creature with a yellow underside, a teardrop-shaped tail, and a singular bright red split antenna. About the size of a cat, it grows quickly and seems to never have it's fill, making it a blight on crops and rural towns everywhere. While fairly slow and weak, they are numerous and can bite if cornered, or shoot strands silky strings to slow down foes or to use as a grappling hook.

Once they have eaten enough, they gather in groups and create a chrysalis to move on to the next stage of their lives, known as metapods, their nests full of coccons being guarded by their adult butterfly form, butterfrees, making getting rid of them all the more difficult.


Hooks (1d4) :

  1. Caterpies are eating a local community's crops, causing risk of famine.
  2. Caterpies are multiplying in dangerous numbers in the nearby forest, they need to be found and culled before they turn into their adult form and become an actual local threat.
  3. The local Caterpie population, a primary food source for many creatures, has been greatly reduced recently, throwing the local ecosystem's balance into peril. Whatever, or whoever, is causing this must be found and stopped, lest hungry monsters come closer to town to feed.
  4. A local alchemist hires the party to gather some of the noxious oil Caterpie secrete from their antennae without killing them, as it remains more potent that way.
