Dorothea Duckfontein Dillworthy, usually known as just Dotti, was a hare and friend of Lord Brocktree. She was known for her terrible singing.

She was the first officer and commander of the Long Patrol. She was a daughter to Daphne Dillworthy and Cramsy and a niece of Blench.

She was not an incredibly clever hare, but was very concerned with correct grammar (at least when speaking to the coarse vermin she believed below her). She also was rather sassy, correcting anyone who called her a "rabbit".

Dotti was one of many to help Lord Brocktree retake Salamandastron from Ungatt Trunn and his Blue Hordes. She was the hare who defeated King Bucko Bigbones in order to gain the support of his court as an army to take the mountain from Trunn. She defeated him through a bragging, eating, and fighting contest. She was specifically trained for all three.

After Trunn's death, Brocktree formed a Long Patrol of the hares at his mountain. He appointed Dotti its commander, with the rank of Patrol General.
