5E D&D Gamma World Monster: Fenkuin
 This is the latest entry in a series of creatures I converted for Fifth Edition Dungeons & Dragons to be used in my son's new Gamma World hexcrawl campaign. You can download all 150+ monsters here
This stark white penguin exudes a slippery oil. 

Fenkuin are mutant penguins adapted to other climates. Their thick, rubbery flesh leaks a slippery form of oil that makes them glisten grotesquely in sunlight. They have barely visible eyes buried in the folds of their flesh, but can see well enough.

The oil that fenkuins secrete makes them unpalatable to most predatory fish but a delicacy to some humanoid species. They are also prized for waterproofing, with enough from a single bird to coat clothing for a medium humanoid, four to coat a canoe, and twelve to waterproof a tent.
