Bill

Bill was Sam's pony, which went along with the Fellowship of the Ring up to Moria in Middle-Earth.

Role in the Lord of the Rings
Bill was bought in Bree after the ponies Merry, Frodo, Pippin, and Sam had brought with them, and all the other horses and ponies in The Prancing Pony's stable had been set free or stolen. Bill Ferny sold them Bill for twelve silver pennies, three times its value. Barliman Butterbur paid for Bill and gave Merry an additional eighteen pence to make up for disappearance of the other ponies.

The Fellowship had thought Bill had been killed by the creature of the lake, however they found it had returned safely to Bree on their return journey. Bill had a small part in the winning of the Battle of Bywater by knocking over his former master, Bill Ferny, in the backside, and thereby freeing the Shire from further entanglements from the foul man.
