Spriggans, also known as HellHoppers, are largish dinosaurs that reside in the deep cavernous valleys of the East African Rift, an otherworldly portal to Hell. Some spriggans have been reported to live in distant Cornball, a county near Mashchester. Spriggans are known for hopping and sliding. With just these two moves in its repertoire, it is greatly feared among the humans. Spriggans are grotesquely ugly and have covered themselves in steel armors. They operate strange machines on their backs that allow them to slide at supersonic speeds, and it is rumored that these mechanisms are derived from the slamming devices of the Dark Slam Gods.
They have the ability to swell into enormous sizes. This usually gets them stuck in tight rooms.
