Nobody knows when Justin sleeps. It just looks like he never gets tired! Justin has loved sports since he was small. No matter what kind of sports it is, Justin will learn it and master it very quickly. He is an avid athlete and everybody's idol.

He’s handsome, cheerful, fit and has the best biceps. Not surprisingly, he’s very popular among girls, but might find him boring to talk to, since he only talks about which team won last night’s race or how cool some brand new sport shoes are. Outside of sports, Justin is actually quite dull…

He spends most of the time working out every day. Justin loves challenging others, which makes him a bother. There’s no one on the island better than him at sports. Because of this, no one on the island wants to be his opponent. And because it’s impossible for him to find a match, he’s always stuck challenging himself!

One day, Whiskers asked Justin, "Why don’t you spend your energy on things that can benefit everyone?" This made him begin helping remove rubbish from the beach and the water. He discovered that he felt the happiest and proudest when he was doing something meaningful for other people.
