The Bloats are an ugly, deceptive race. Physically, they're much bigger than Zoombinis and Fleens. Many years ago, they arrived on Zoombini Isle, offering trade and partnership. However, before long, they had turned the Zoombinis into slaves, driving them to escape. After all the Zoombinis left Zoombini Isle, they could do nothing to help themselves on the island, and found it useless. They left the island leaving it barren and wasted, and never bothered the Zoombinis again.
