believe it or not this is a character that came to me in a dream.
you know the schtick, haunted animatronic at an old abandoned theme restaurant. She's got some quirks though.
First of all her body was never meant to be able to move around. Her part in the stage show was to pop out of a stump and enforce the rules of the forest every now and then and be kind of like a party pooper to the main performers. Once she was haunted though, the ghost managed to form the big rubber stabilizer at her base into a lower body and rip free from the stump. She didn't really have legs but she managed to fashion some out of some fresh-out-of-the-box spare parts in the maintenance room which is why they're so much newer and shinier. She spends most of her time roaming the halls of the restaurant and spooking anyone who sneaks into the place for fun. Her favorite thing to do is to "swallow" people up into her big round body and seal them in until morning. Not only is it funny but she likes the feeling of people knocking around in there. Any time else she's probably hacking into the power grid to get the arcade machines to run again.

Nobody knows who the ghost inhabiting her is. The only recorded death in the restaurant was a part time technician who was dared to swallow one of the ball pit balls. It ended predictably.
