Elephanko was a Lemures used by Hawk's Eye while targeting Princess Rubina for her Dream Mirror. Gum Mario was her brother-in-law, but she claimed to have disliked him, and even thanked Sailor Moon for getting rid of him - despite the fact that she, too, would join him when Sailor Moon killed her. She performed a circus trick that involved an elephant standing on top of her.
