Over the years to many to count. He's been making fish float since he hit puberty. His farts eventually got so smelly some took out the entire pond! Shrek would stick his butt in mud, and Fart suffocating worms making them come up for air then scoop them up and put them in his underpants. Shrek then jumped in a pond and stood still. Fish started coming up to shrek and eating the worms from his underpants. He then noticed every fish was eating off him and he made an evil grin. He then farted causing many fish to die instantaneous. Others tried swimming away but his fart was to big and stinky. He then observed the fishes just die in schools and would laugh and take a couple out.
