Triangle of Insanity is an expert track in Bloons Tower Defense 4 Expansion. This track is considerably hard as the Bloons only move around the outside, and that makes the track extremely short. It has three entrances and exits. If this track is completed on Medium or Hard, the supernatural speciality will be unlocked.
