Cinnamon

Cinnamon is the pet fish of Dr. Ogden Wernstrom. He was used to demonstrate Wernstrom's invention, the Reverse Scuba Suit, at the Academy of Inventors Annual Symposium. Wernstrom and Cinnamon easily beat Professor Farnsworth, who presented last-minute designs for the Smell-O-Scope. Despite his ability to fetch while wearing the Reverse Scuba Suit, Cinnamon has yet to master the "Sit" Command.
