You have to eat it and turn into it, and then leave the house, coming to the hallway
i dont see where to find the option to turn into something or leave the house
in the rabbit’s bedroom, you can turn into her when you eat her
how big do i have to be to eat her? i think i got to around 3 meters big
you need to grow 3 meters tall and when you jump on her bed there is a button - eat rabbit
