Jawhne Dough, also known as The Studiogrounds Vandal, is a character in Broadside Beach. He's one of the only two Starlings that was not converted from a human, instead forming on his own from excess matter given by the previous four. Though little about him is known, what little has been revealed is that he routinely broke into the Studiogrounds theme park, and posted about his findings against the Broadside Animation company on an internet forum in the 1990s. To this day, he carries a powerful grudge against Broadside's CEO, Mark Mullins.

In Shipwrecked 64, he appears in a top hat and tuxedo, going by the name J.D., to help guide Bucky Beaver on the path to the game's most positive ending.
