The tool is a long and jumping rope-like with the rope colored light pink. Each end of the rope appears to have handles attached, which are black with large silver-colored spheres.
When the holder is transformed by using the Mouse Miraculous and an additional Miraculous, the rope changes color. The rope is red, black, or orange, depending on whether the holder is also transformed with the Ladybug, Cat, or Fox Miraculous, respectively.
When the jump rope isn't in use, similarly to Ladybug's yo-yo, it's wrapped around her waist or hips.
Although it's unknown what the full abilities of the jump rope are, it does aid in its Miraculous' special superpower, Multitude, which allows the user to shrink down and create numerous clones of themselves for an unknown amount of time.

- The Mouse Miraculous tool first appeared in concept art of Marinette transformed with the Mouse Miraculous at the 2018 Comic Con Experience panel on December 6, 2018.
- The jump rope is the seventh Miraculous tool required for a superpower activation, following Ladybug and her yo-yo, Rena Rouge and her flute, Queen Bee and her spinning top, Carapace and his shield, Mayura and her hand fan, and King Monkey and his Ruyi Jingu Bang.
- This, along with Ladybug's yoyo and Queen Bee's spinning top, are based on real toys.
- The way the Mouse Miraculous holder is wrapped with the jump rope while using Multitude might be a reference to the way Arthur shrinks in Arthur and the Invisibles.
- It's the second tool to be a weapon and accessory as when the jump rope isn't in use, it acts like a mouse or a rat's tail. The first one is the shield, which acts as a turtle's shell on Carapace.
