Wav-el, Fish, and the Spookies - Vivienne Thompson Clements - Bog

Wav-el loves his ocean friends and especially his best friend, Fish. He'll do whatever he can to protect them from harmful pollution that people, who he calls the Feet, cause to the water. He has seen the danger many times that his friends have come into by getting hit by the trash thrown into the water, and other times his friends got tangled up in plastics, bottles, and cans causing damage to their fins, and they wouldn't be able to swim, and the entrapments keep them away from their families.
Wav-el keeps watch over the ocean all the time making sure that the water stays safe for his friends.
