Trivia

 * His character is very unique, as he seems to be a child, because he is a block shorter than all other NPC's and players, and talks a bit like one. If that is the case, he's the only child NPC in the game. He's also the first NPC to do quests.
 * The Quest for the Clownfish is a reference to the Disney movie, Finding Nemo.
