Sharp-ears was one of the ponies Merry had provided for the journey from Buckland to Imladris. When the Hobbits stayed in the house of Tom Bombadil, their horses befriended Bombadil’s pony, Fatty Lumpkin. After becoming frightened in the Barrow-downs, they ran off in search of their friend. Tom was able to recover them, calling them by the names he had given them. Sharp-ears was later driven off while the Hobbits sought rest at the Prancing Pony Inn in Bree, though he was later recovered by Tom Bombadil, who sent him to Barliman Butterbur.
