Birthday Fairy(given by Jay)
Abby's birthday fairy
Celeste is an energetic, optimistic, fun-loving, and easy-going person, but not air-headed, rather wise; she gave Abby her 16 magical candles to teach Abby about how important her family is and to rush about growing up.
A majority of her character is ambiguous and mysterious, it is clear that she can warp reality, as she did multiple times in the film such as infesting the family's house with wasps, making Abby's dream boy appear her house, giving her a perfect red car, etc.
