There is a new costume available in the Poptropica Store this week. It’s the Hammerhead Costume and it looks a lot like the Sharkboy and related costumes in the game but this one has a head piece that looks like a hammerhead shark with two big eyes bulging out of the sides. Sharks are cool, especially in the summer.
And as the Poptropica Creators also point out in the official blog, there are lots of places in the game to get shark items. The best place to go is Shark Tooth Island. You can use the costumizer on Shark Boy inside the museum to get a regular shark outfit and the street vendor outside sells dorsal fins!
