Arboreal Gulper

The Arboreal Gulper drops from Humon'gozz in northwestern Ardenweald. In order to spawn Humon'gozz, players must first loot an Unusually Large Mushroom from any mob in Ardenweald, Mists of Tirna Scithe, or De Other Side, and then plant the mushroom in the pile of Damp Loam before its 20-minute duration runs out. This will spawn a Rapidly Growing Mushroom which in turn transforms into Humon'gozz.

The wood and foliage growing atop the this toad is a natural part of its body - helping it siphon anima from the air to nourish itself.
