A resilient breed of tree monster that takes its name from the type of white peeling bark that adorns it. They seem to be much greener and more luscious than most Mocks, and prefer colder climates. Its black and white colors may mean it is related to Hopper or even Jill.
Its Japanese name is Shirakaba (シラカバ), named for the Betula platyphylla, the Japanese White Birch Tree (白樺). This is a type of tree that grows in many countries that has white, paper-like bark that peels back to reveal black nubs underneath.
