Frogblood was a rat captain in Cluny's Horde. Frogblood and Scumnose were in charge of rounding up soldiers to serve under Cluny's command, especially rats, who they considered to be superior, weasels, stoats and ferrets. They managed to get a hundred recruits, pressed-ganged into service under threat of beating or death. Frogblood and Scumnose also led a group of soldiers into scaling Redwall Abbey during the siege. Frogblood was slain by Matthias with the Sword of Martin in the final struggle for Redwall. He was the only captain to have no dialogue. He was killed off-screen in the final battle.
