The Mouse Miraculous is a pendant necklace that, whenever Mullo inhabits it, transforms the wearer into a mouse-themed superhero with the power of Multiplication.
To activate the necklace, the user must speak the transformation phrase: "Get Squeaky".
In the future, when the situation calls for it, the pendant necklace will temporarily be lent to Mylène Haprèle, who will use it to transform into Multimouse.
The Mouse Miraculous is a pendant necklace that is circular and dark gray with lighter gray markings and five pink rats in a circle on the front of it.
When in camouflage mode, it appears as a bronze Chinese coin when worn by Marinette, and a golden pendant when worn by Chloé.
