The Hedron is an obstacle in Super Paper Mario encountered in the Outer Limits. Its name comes from the geometry suffix -hedron. The Hedron is a rotating, blue rectangle with a yellow outline. If Mario and co. are hit by it, he takes damage. Hedrons are often encountered in groups and must be avoided with quick, evasive, maneuvers. Flipping to 3D does not help, either, as the Hedron exists in the third dimension as well. The Hedron can be destroyed, but doing so takes 256 shots from Squirps, regardless of the player's current attack.
