Bombur:

One of the twelve Dwarves that accompanied Thorin on the quest for Smaug's treasure, Bombur was notoriously fond of his food. During the quest, he fell in the enchanted river in Mirkwood. He slept for several days at least. Bombur survived the Battle of the Five Armies, and probably the War of the Ring though he was very fat and most likely did not participate in the defense. No date given for his death.
