Swim Trunks (swimwearicus rips-easilius), labeled The Athlete, is a male contestant on Object Trek. He was placed on the Floppy Rabbits.
Swim Trunks is best friends with his twin sister, Bathing Suit. He's a terrific athlete, especially where swimming is concerned, but being made of fabric, he has a bit of a tendency to rip easily.
In How It Began, Swim Trunks was the first one to be picked onto Pie's team. She figured that Swim Trunks, being a good swimmer, would be useful on her team, since getting to Objectoo would most likely involve swimming.
During the contest, Swim Trunks crossed the river together with Bathing Suit. His team eventually lost, putting him up for elimination.
