Originally using the persona, "Flippy", Dr. Blowhole performed tricks at the aquarium in Coney Island. His signature trick was jumping through "The Ring of Fire", which may be what caused the cyborg replacement on his left eye.
As revenge on the humans, Dr. Blowhole sets about to create his own "Ring of Fire". This was destroyed by King Julian, who was acting as a double agent.
Dr. Blowhole returns sometime later to apprehend Skipper and wipe his memory. Leaving Skipper on a deserted island, Blowhole uses his memories to locate the HQ. A series of mishaps, and unexplained singing, allows Blowhole to nearly take control of New York City. However, he is once again foiled by the Penguins. His own memory is wiped away, and he is forced to resume his former role as, "Flippy".
Dr. Blowhole has skin that is surprisingly pleasent to the touch and a beautiful voice "for villianous scum". He mispronounces the word "penguin" instead saying, "PEN GUUU WIN." Kowalski had determined that this is "just to tick the Penguins off."
