Trivia

 * Despite the Sea Creature Guide referring to this creature as Sea Emperor, its in game name reads instead as The Emperor.
 * There was a bug with the Ink Wand's ability and the Explosive Bow's explosive arrows, where if the Sea Emperor is killed by either of these it can drop multiple skulls and have a higher drop chance of rare items. This is because the Sea Emperor is technically two mobs, and the ability kills both of them at once, causing double drops. This was fixed in the Community Update, patch 0.9.
 * The Sea Emperor targets other players if it has been hit by another player. If all other players that have damaged it are killed, it targets you.
 * Bringing a Sea Emperor to Jake in the Mushroom Desert will allow the player to purchase the Golden Ball.
