Major Cuthbert Blanedale Frunk was a perilous Long Patrol hare who served under Lord Mandoral Highpeak. His daughter Petunia was brutally murdered by sea-raiding vermin on the Salamandastron shores. After his daughter's death, Frunk hunted down the murderers, disposed of them and captured their ship, re-naming it the Purloined Petunia in her honor. He was nearly killed in the fight, suffering a multitude of wounds that left him badly scarred and cost him half an ear.
Due to his daughter's death and his terrible battle injuries, Frunk experienced a deep mental trauma that developed into a dissociative identity disorder. He frequently changed personalities and identities, depending on how he was feeling. In addition to his regular identity as the Long Patrol Regimental Major, he also believed himself to be the following:
- Cuthbert Frunk W. Bloodpaw - a no-nonsense sea otter captain, the terror of the high seas
- Log-a-Log Boodul - a Guosim Log-a-Log shrew
- Lord Brockfang Frunk - a wild hunting badger
Frunk wore a waxed mustache and a monocle, and carried a sabre and a swagger stick in his role as Major Frunk, although he changed his outfit to match his current personality, sometimes combining them when he was more than one at once. Despite his Bloodwrath and personality disorder, Frunk had not lost his sanity, he could carry on intelligent conversation, and was a clever battle tactician.
Frunk was allowed more leeway than any other hare in the Long Patrol from Lord Mandoral Highpeak, due to his deep trauma. He was the only hare allowed to sing bloody ballads at the dinner table. Many hares who did not understand Frunk's behavior nicknamed him "Blood'n'guts Blanedale." Lord Mandoral referred to the dangerous hare as the "Deathseeker," saying he was always looking to get himself killed in his wild exploits.
Frunk was responsible for guiding Tiria Wildlough to Highpeak, who gave her the High Rhulain armor. Along with other Long Patrol hares, Frunk and Tiria sailed in the Purloined Petunia to Green Isle, home of Tiria's otterclans.
While at Green Isle, Frunk arranged all the battle plans for the otterclans and Long Patrol; they were a success, as Riggu Felis and his army of cats were defeated easily. Later, the force encountered Riggu's absconded son Pitru with a small army, blocking their way home to Holt Summerdell; Frunk slew Pitru and several of his close followers in an all out berserker rage.
He was wounded in the battle, but jumped into the Deeplough, taking several cats with him. In the process, he encountered the hideous Slothunog. Frunk jumped on and violently killed the monster; its body sank into the lake, carrying the hare with it.
Mandoral Highpeak allowed Frunk's name to live on in a ship he later captured, naming it the Fearless Frunk.
