Benjy was a young male squirrel who was orphaned by rats under command of the Foxwolf Urgan Nagru. He was marooned on the Island of the Wrecked Ships with a young mouse, Wincey, and a tiny otter, Figgs. They lived as an adoptive family in a small tent on the island near the cove of shipwrecks, though the trio originated from Southsward.
The three orphans were cared for by Burrom, who had been on the ship with them before it wrecked and allowed the little ones to call her "father" because Wincey never knew hers. After Burrom died from a head wound, Benjy kept her death a secret from his sisters, and looked after the young ones until they encountered Joseph the Bellmaker and Finnbarr Galedeep. The orphans were taken aboard the Pearl Queen, and Benjy's knowledge of Southsward allowed him to act as a scout when the crew finally landed in the area.
Benjy and his sisters were adopted by Gael Squirrelking and Squirrelqueen Serena after the Battle for Southsward.
