Bubblegum
Nobody really remembers when Bubblegum showed up at the carnival. One night she was just there, standing off to the side and watching everyone go by.
Bubblegum doesn’t talk much, but she’s always looking for a new friend. She might offer you candy, especially if the Tooth Fairy needs help collecting. If she follows you into the dark, don’t worry about losing her. She won’t lose you.
