Honey

Honey is a yellow goo-like substance that is found in Super Mario Galaxy in the Honeyhive Galaxy, but only on a single path. It is very sticky, to the point where it causes Mario or Luigi to stick to it, making him able to do only low jumps. The honey path is part of the track Mario/Luigi must travel across to reach the Power Star in the mission Honeyhive Cosmic Mario Race, where Cosmic Mario or Luigi gets stuck in the honey.

Honeybees can be found gathering the honey in buckets, claiming it is heavy. Honey also appears on certain walls that Mario/Luigi can stick to when in bee form.
