Little brother can play with big brother if he brings him a unicorn… a winged lion… a triceratops. Incredibly, little brother actually finds these mythical and extinct creatures. So, for a truly impossible task, big brother asks for a snappenpoop. But snappenpoops do exist, and some are little brothers, bringing a fantastic twist to this hilarious tale!
