Blango

A Pelagus covered entirely in white fur. Known to move in packs and led by a Blangonga. The Blangonga exerts tight control over the group, and any call to gather will be met immediately by the rank and file Blangos.
A white Pelagus that moves in packs in the Snowy Mountains. It jumps forward, backward, and to the sides and moves in tricky ways, but its health is low, so alone it is not much to fear. It may also appear when called by a Blangonga.
