Rufus is a red fiddler crab. He does heavy damage to aliens that you lure to the bottom of the tank. He is unlocked after completing Tank 2-3.
When you lure an enemy to the bottom of the tank, Rufus will proceed to swipe at it with his claws, doing heavy damage. He is very good against Destructor and Ulysses, as he attacks them immediately. He is one of the 4 attacking pets, the others being Itchy, Gash, and Stanley.
Rufus started his career as a dance instructor, teaching people how to do his patented pop and lock arm routine. When his dance studion burned down in a freak accident, Rufus became a mercenary for hire, using his dance skill to amplify his already potent fighting ability.
Rufus is relatively useful against Destructor and Ulysses. Other aliens have to be lured to the bottom of the tank for Rufus to be able to attack them, though. Though Gash does the heaviest damage agains aliens, he doesn't have the danger of eating your guppies.
