Speedwell was a rabbit who originated from Sandleford Warren. He left the Warren with Hazel, Fiver, Pipkin, Bigwig, Hawkbit, Dandelion, Blackberry, Silver, Acorn, and Buckthorn, to start their own warren which eventually came to be known as The Watership Down Warren. At one time he wanted to go back to the Sandleford Warren but was forced to continue on by Bigwig. He was very good friends with Acorn. He appeared in Watership Down (book) and Tales from Watership Down (book).
