Mambar (basic stage)Boomrslang's Phoenixdex Entry
Boomrslang slither along tree branches in search of prey or a nice spot to relax. If they like a nearby tree more than their current one they launch themselves from the branches in the shape of a boomerang and spin into another limb, then relax and slither away.
Actually, their special steely scales allow them to stiffen into almost any shape they can make, not just boomerangs. They are nearly indestructible when they coil up tightly before hardening, for example. They have a hard time making proper shapes right after eating a large meal, however.
