Shelly

Shelly is Tonjit's horse and an animal of Long Ring Long Land.

Appearance
Shelly is a female horse, but she doesn't resemble any other horse, as her neck and limbs are very long. She somewhat resembles a giraffe more than she looks like a horse.

Davy Back Fight Arc
While visiting Long Ring Long Land, Luffy, Usopp and Tony Tony Chopper found a horse named Shelly near a house. She was waiting for her master Tonjit to come back for ten years. Once Tonjit returned, she was happy to see him. But the reunion was cut short because Foxy wounded her with his gun. This action caused Luffy to participate at the Davy Back Fight game.

In the anime, instead of shooting Shelly with a conventional gun, Foxy shot Shelly with a net gun in order to get Luffy's attention. As the Davy Back Fight was extended, the first member of the Foxy Pirates Luffy claimed was Shelly, in order to return her to her master.

After Luffy won the Davy Back Fight, he and the rest of the Straw Hat Pirates returned to check on Tonjit and Shelly and Shelly seems to be recovered from her wound. Then, Aokiji appeared and used his Hie Hie no Mi abilities to freeze the seas so that Tonjit and Shelly can rejoin their fellow nomads.

Two Years Later
She was seen next to Tonjit, playing with Tonjit's grandchildren.

Trivia

 * In the anime, instead of Aokiji, Tonjit's grandson appeared from the ground, riding a mole which gave Tonjit and Shelly transport.
