Mylène Haprèle/Polymouse

While the rest of the girls had moved to a "Free-for-all" on Ultimate Mecha Strike II now that their champion was out getting snacks (or so they thought), Mylene was getting herself some water.

Mylene was dressed in a bright-green, full-body onsie, leaving her hands, feet and head exposed. Around her neck was a necklace with a navy-blue pacifier which he had in her mouth. Mylene wasn't the most social person, so whenever she was lost in thought or if her anxiety started getting to her, she would suck on a pacifier.

Everyone had pacifiers and would use them from time to time. In-fact, Juleka had one in her mouth right now as she kicked the other player characters out of bounds. Mylène had accidentally stolen one of Ivan's during one of their dates and, having forgotten to bring her own for the sleepover, had decided to use his before returning it.

Mylene had rummaged through Marinette's cabinets and filled one of her sippy-cups with water, only to drop it by accident when she saw Ladybug tapping at the nearby window. Thankfully, the sippy-cup held when it hit the ground.

"Mylène, thank goodness I found you," said Ladybug as she opened the window, letting herself in.

"Ladybug? What are you doing here," asked Mylène as her binky fell out of her mouth.

"Kim's been akumatized and he's got a sentimonster that can clone itself. We need Polymouse."

"I-I don't know, Ladybug. There's a bunch of other girls upstairs that would probably be better for it."

"Nonsense. You have experience using the mouse miraculous and I don't know how long Cat Noir can hold them off."

Ladybug opened her yoyo and pulled out a necklace.

"I bring you the Miraculous of the Mouse, which gives you the power of Multiplication. You will use it for the greater good and return it to me when you are done."

Mylène stared at the miraculous, then to Ladybug and the mouse kwami waiting for her to take it.

She took it. She put it on and spoke the phrase.

"Mullo, Get Squeeky!"

Magic washed over her body. Her onsie turned from dark green to light grey with bits of pink. A hoodie with mouse-ears covered her dreads. While her pajama onsie was baggy, this super-suit clung to her body like a second-skin, the curve and bulge of her diaper gone. As she felt her magic jump-rope curl around her waist like a makeshift tail, her miraculous generated a makeshift nub and a surrounding guard that looked like a pair of whiskers before she put it in her mouth, the necklace turning into a pacifier.

With her miraculous occupying her mouth, she gave Ladybug a hesitant thumbs up.
