Long John Slither is the captain of a pirate ship on which Kevin Keene, Link, and Pero found themselves after leaping through a warp. He believed Pero's lie that they were looking for treasure on Skull Island, and took their map when Count Gruemon's henchcats sneaked aboard the ship and made him slip on a bar of soap. Pero, however, took the map back and cut the rigging as Long John Slither and two of his crew members climbed after him, dumping the pirates into the ocean.
