Dr. Blowhole

Dr. Blowhole is one diabolical dolphin. This marine mammal determined to rule the world. With a love of high-end technology and fresh fish, he wants nothing more than to defeat the penguins, especially his nemesis Skipper. Humanity made him jump through one too many hoops, and now he's determined to make them pay with his mad science and army of crustacean cronies.
