Gundy 'Gunsby' S. Calsome is an Alpheus deuteropus pistol shrimp from the world of Bikini Bottom. He was a former mobster infamous for his loud snapping and his very strong claw which can fire bubble shockwaves known in real life to stun prey, and for it's lethal punches. But after 12 years of tormenting his hometown of Shrimp Valley, he was injured in the claw and some of his legs by the police and ended up dying in the caverns of the Ring of Fire trying to escape. He was eventually resurrected as a zombie by Krakatoa, who improved his natural abilities and made him his top bodyguard.
