Durby Furrel was a little male mole resident of Redwall Abbey. He was the son of Mrs. Furrel. Durby was mischievous and didn't like taking baths because he believed that he would shrink. Because of that, Durby measured himself after taking baths.
He was a friend of Feegle. After a Wall Race, Durby, Feegle, and Trey were playing in the ramparts of the Abbey. He and Feegle fell the ramparts and were captured by Poskra. Poskra was killed by Vallug Bowbeast. Durby was then taken captive by the ferret and Eefera, but they were rescued by Mhera, Broggle, and Fwirl.
