An Arantula is a black spider-like creature that lives in the Pit of 100 Trials. Arantulas are relatives of Piders, and are even named similarly: the Pider's name is "spider" without the "S", and Arantula comes from "tarantula", without the "T". They attack in the same way that Piders do, just with more power.

In Super Paper Mario there is a Sammer Guy called "Hairy Arantula in the Grass". His name is a reference to the Arantula.
