There was a time when HIPPO had lots of hair!
So she was always harrumphingly hot. All she wanted to do was to splosh in the Waterhole, but this was forbidden... water was for fishes. Then one night when HIPPO is sleeping a spark from the fire sets light to the end of her hairy tail! HIPPO is on fire! SPLOSH! HIPPO jumps into the Waterhole. When HIPPO surfaces she has no hair, not a single hair on her hide! And from that day on HIPPO is allowed to stay in the cool waters.
