You find a stray stand but its not a stray. This stand is Akemi Fujiwara's stand. But its just wondering around the place.

You can hear the metal gears as Rabbit hole walks. The Pink bunny animatronic is cute looking. There is no way this could be Akemi's stand.

The bunny has an invisible mouth but it looks like it doesn't have a mouth. Nonetheless, the stand is seen playing with some stuffed animals and building blocks.
