Belinda

she would be one of the mini "side stories" after being encountered in the woods around ben and mel's house! the group would think she was there for some kind of attack and initially go up to fight her, but when she gets embarassed and reveals that she simply doesn't have a home and just "gets weird" under the moonlight, they invite her to stay at the house and she just becomes a recurring joke character [as well as an explanation for who cleans up the house after their antics + watches it when the group is gone!] since she can only turn under moonlight, she is fine if she is in the house and the windows are closed :D
