Valcean beast

We don't know the name of this thing.
But we do know where it came from. So we're using that to title the page logically. If you know a better, more precise name, tell us.
A Valcean beast was a unnamed predatory species, native to the planet of Valcea. They resembled a cross between a bull elephant and rhino, with translucent, glass-like skin, so it was possible to see its organs. One Valcean Beast attacked Iris and her friends, but Barbra somehow managed to kill it. (PROSE: Enter Wildthyme)
