The Horse Girls are a group of kids that reside in the Meadow in The Creek. They are obsessed with all things horses, wearing horse riding clothes and even growing out their hair as a Mane. They are very territorial to the Meadow and threaten to buck any trespassers.

She wears a white shirt with an image of a horse on it, and also wears pink pants with blue boots. She has a gap between her teeth.
Melissa: A member of the Horse Girls who is very enthusiastic about horses. She appears to have peach skin with yellow earrings and has green eyes, and also, she is the only member who has an eye color. She wears a short-sleeved white shirt, wears long brown pants, and wears some black boots.
Maney: Maney is a member of the Horse Girls who has a crush on J.P. She is friends with Kelsey and pretends to be her noble steed by giving her piggy back rides. She appears to have dark peach skin and long, black hair, as if she has a mane. She wears a sky blue sweater with an image of a giraffe on it, and wears magenta leggings with white boots.
