 * Sea Creature Chance is only active when the pet is rarity.
 * The look/texture of this pet appears to be slightly lighter, if not identical to the Bat Artifact.
 * Since at level 100 it will increase only 50% damage against Spooky Mobs and every weapon deal 1 damage, it will only affects: Blast o' Lantern, Ghoul Buster and Pumpkin Launcher.
