Mouxygen

Mouxygen (Oxygen Mouseus) scampers around the underbrush of ChemCraftian forests.

Coloring
For camouflage purposes, Mouxygen is invisible in normal tempuratures. However, in extreme cold, Mouxygen becomes more languid and turns a shade of blue. This is thought by ChemCraftian scientists to be a defense mechanism; if tempuratures do sink low enough, there is likely to be snow/frozen water, and blue would aid Mouxygen in blending in.
