When players lure an enemy to the bottom of the tank, Rufus will proceed to swipe at it with his claws, inflicting heavy damage. He is exceptional against Destructor and Ulysses, as he attacks them immediately. He is one of the 4 attacking Pets, the others being Itchy, Gash, and Stanley. Although Gash does the heaviest damage agains Aliens, he doesn't have the danger of eating your Guppies.
