Trivia

 * Mirror of Malice was silently changed during February of 2019 so that the Dark Stone Jellies would magnetize towards the current Cookie instead of floating in the air and having to be touched to be collected.
 * Mirror of Malice vaguely resembles Pomegranate Cookie's mirror, although painted with a darker color.
 * According to the Korean name and story of this Treasure, the mirror is said to host a vengeful spirit, and has the capability to absorb both the darkness and souls.
 * The English translation however only relegates the mention of a vengeful spirit in the Treasure's skill description, as a "Malicious Spirit" Jelly.
