Tales of Tolgard
Su-monsters are monkey-like magical beasts with dirty gray fur. They have black tails and faces, and their paws are blood red. They have prehensile tails that they use to swing from limb to limb or to hang upside down. Su-monsters inhabit forsaken wilderness areas and subterranean lairs as well.
All four feet of a su-monster are prehensile and armed with long and extremely sharp claws. Su-monsters are at home upright or hanging upside down—the latter being one of their favorite methods of lurking for prey. Su-monsters prefer to attack in this manner since they can bring all four claws and their bite to bear on their opponent.
