Castle Lemongrab

Castle Lemongrab is the place where the Earl of Lemongrab lives. It is in Lemongrab. Princess Bubblegum stuck him in this place so that he would stay away from everyone. It can be inferred that he has lived nearly all of his life in this castle. Seeing as how the earl of Lemongrab was so irked by Princess Bubblegum's Castle being unclean, Castle Lemongrab is likely a very clean place. Jesse Moynihan claims that Castle Lemongrab has the potential for exploration in a future episode of Adventure Time.
