Shark Boy is a male dressed up as a shark inside the Shark Museum on Shark Tooth Island. He is one of the most popular characters, and was an alias of the Poptropica Creator Nate Greenwall.

As of April 2014, Shark Boy presumably changed his avatar name to Shark Guy and his username to sharkguycreator. All external appearances of Shark Boy were covered up as well. Read more about the disappearance here. While this may be in fact the real creator, his name was not officially changed and therefore we still refer to him as Shark Boy.


Shark Boy is a grumpy character - while the first two questions you ask him are answered politely, he soon grows tired of you, and admits that he's not a real shark, and is just a guy trying to make a living. His shark outfit has visible stitches and a shark fin similar to the one you can receive from the Shark Fin Vendor. He holds a fish that is seemingly dead. With relaxed eyes and an unhappy smile, he's every kind of melancholy and somewhat sad or depressed.


You'll find Shark Boy inside the Shark Museum on Shark Tooth Island. He's on the bottom floor, inside a pool of shallow water. When prompted, he will answer your first two questions, and then will tell you that he's just trying to make a living.
