The Spa Ponies are twin earth ponies who work at the Ponyville day spa. Their appearance is similar to the G1 Surprise Twins Babies ponies. Their names are believed to be Lotus (blue coat) and Aloe (pink coat).
One of the spa ponies first appears in the episode Bridle Gossip, and later they appear together in Green Isn’t Your Color. In the former episode, the spa pony only appears briefly in the final scene, asking Zecora for the ingredients of her herbal bath. She speaks with a strong but indistinct accent.
The spa offers many services in Green Isn’t Your Color, such as massages, mud baths, seaweed bath wraps, steam rooms, and even horn filing for unicorn ponies. Rarity comes in for her “usual” and returns for a second time as soon as she’s finished. One of the spa ponies did not seem to notice that Fluttershy was not a unicorn pony when she attempted to give her a horn filing regardless before realizing her mistake. Another pony works at the spa, and he briefly appears in this episode, giving Rarity a massage.
