Giant Grouper

Groupers are large fish, which use their large mouths to “suck” in prey. This special “gulp” ability gives them a free bite attack with a +4 bonus to the attack roll. Mundane groupers can grow to almost 8 feet and weigh up to 880 pounds, although most are much smaller. These fish don’t usually pose a threat to swimming humanoids. Giant groupers, which grow to 1d20+10 feet long and weigh 1d100+50 pounds per foot, do.
