One of the five ponies that Merry Brandybuck had ready at Crickhollow for the journey of the Ring. White-Socks was ridden by Merry to the House of Tom Bombadil in the Old Forest. Once there, the five met Tom's pony Fatty Lumpkin. When frightened at the Barrow-downs, they rushed to find him. In Bree, the Squint-eyed Southerner let them free in hopes to delay te Hobbits leaving, and more importantly the Ring's leaving. White-Socks and his four friends rushed to Fatty Lumpkin again, and Tom cared for them and sent them back to Bree to work for Barliman Butterbur. The ponies were later found after the deconstruction of the Ring.
