Floggtail was the male sea rat first mate of the Greenhawk. He presented a plan to capture Luke the Warrior's tribe, which the Sea Rogues thought consisted of only two members. The plan, invented by Wippback and Scritchy, consisted of sneaking up on the tribe members on shore and murdering them. Reynard Chopsnout was opposed to this plan, because the Greenhawk was taking on water and might sink if the crew took the time to prepare an ambush. Neither plan would give them a fighting chance, because the Luke's tribe had prepared for every eventuality.
Floggtail was a very minor character, little is known about him.
