Eyelashes is the camel who accompanied the Straw Hat Pirates during the Alabasta arc.

Alabasta Arc
He would only let Nami and Vivi ride, and, in her admiration, Nami named him "Eyelashes" but he refused to let anyone else on, prompting the rest of the crew to beat him up and label him as a "Pervy Camel" (or "ero-camel", because he only let the two women ride). The crew only knew of that by Chopper's translation.

He disguised himself as Vivi by riding a Spot-Billed Duck and wearing a white cape. He was paired up with Usopp and got chased by Mr. 2. He was as weak as Usopp since Mr. 2 only needed one second for each of them.

After the Alabasta arc, Eyelashes was ordered to be given special treatment, as well as being allowed to join the Super Spot-Billed Duck Squad (even though he is a camel), as revealed on the cover of Chapter 271.

Two Years Later
After the timeskip, he is seen walking around with Vivi and Carue. He and Carue are eating apples as everyone waves at them. He is also seen wearing a helmet.

Anime and Manga Difference
In the manga, the Straw Hats first met Eyelashes when they saved him from a Sandora Lizard. While he already had a saddle on his back, it is unknown who his original owner is or where he came from.

In the anime, he was originally from Rainbase and was bringing weapons back and forth to the rebels from Nanohana to Katorea. During one of these trips he and Chopper became acquainted since Chopper was brought to Katorea by accident and Eyelashes smuggled him back to Nanohana. They were reunited when the Straw Hats save him from the Sandora Lizard as they did in the manga.
