Cabin boy Jenkins was a crew member on the Lady Lumbridge, a ship that a player buys during the quest Dragon Slayer. Despite the ship's changing hands, Jenkins continued to serve aboard.
He comes with the player and Ned when the Lady Lumbridge sets sail towards to Crandor. However, nearing the island, Elvarg swoops out of the sky and attacks the ship. He is incinerated by Elvarg's dragonfire, along with much of the ship. He has only 100 Life points, as seen when he dies.
