Trivia

 * In an episode, Marinette builds a chest with the same shape and color theme to keep the diary safe from being read and revealing her secrets. If someone tries to get Marinette's diary while it's open, the chest will close and lock, also being able to trap someone's hand in it. The only way to unlock it is with a key of Marinette keeps with her.
