Mustafar Lava Flea
this was a species of immense insects, used as mounts by the inhabitants of the planet Mustafar. The six-legged lava flea walked in a head-down position, with its armor-plating torso held high enough to place a fire-resistant saddle at its crest. The eyes of the lava flea were protected by nictitating membranes that could cover the eye and protect it from dust and ash. Individual lava fleas were agile creatures that moved about on the cooling lava, and were capable of leaping almost thirty meters if needed. The average lava flea stood over four meters tall when fully grown, having started out life as a half-meter-long, worm-like larva. In the larval form, a lava flea fed on the rock dust that filled the underground lairs of their hive. At about a year in age, the larva encased itself in a cocoon, emerging months later as an adult flea. The name "lava flea" was given to the creature by offworlders who established lava processing factories on Mustafar, since the name used by the Mustafarian race was virtually unpronounceable to other races.
