Lava snake
From Tardis Wiki, the free Doctor Who reference
Lava snakes were a type of creature regularly battled by Church clerics in the 51st century. While Angelo found hunting down a Weeping Angel better than hunting lava snakes, Christian rebutted, "Actually, lava snakes weren't that bad." (TV: The Time of Angels)
Chiyoko asked for a lava snake as a pet, however, Ranesh objected to this. (COMIC: The Phantom Piper)
