Foosh

The Foosh is an unaggressive organism adapted to life in the Tundra.

Biology
The Foosh (Folium epicaustum) is a simple phytoid organism characterized by its leaf-like body and its unusual method of obtaining chemical energy. Incapable of photosynthesis, the Foosh survives by inducing combustion in certain materials in its environment (most frequently pieces of coal). The Foosh will drape itself over its meal, inject it with a chemical cocktail what initiates the exothermic reaction, and stay in place until it has absorbed enough energy, at which point it will move on. The Foosh itself is invulnerable to attacks from Trebhum.

The foosh's heated rocks allow Trebhum without the fur mutation to survive next to them in the Tundra, and can also be carried as a portable heater, if the Trebhum who is carrying it doesn't mind having a burnt trunk. This rock also gives the iridescent skin to Trebhum that are near it.

A fragment in the Trebhum genetic memory cluster suggests that the Foosh was a popular subject of children’s songs.

Behaviour
The Foosh live a very peaceful life of jumping on rocks and heating them up. Otherwise, they ignore everything else as they are invulnerable to every predator in the Tundra.
