Laboon

Affiliations: Rumbar Pirates (former); Crocus

Laboon is an extremely large whale (of comparable or greater size than the monsters in Calm Belt), native to West Blue, whom the Straw Hat Pirates encounter immediately after entering Grand Line. Fifty years earlier, Laboon had been left at the bottom of Reverse Mountain by a group of pirates who had befriended him. Since his species travel in pods, he had forged a powerful bond of friendship with these pirates, and he patiently waited for them at Grand Line's entrance. His caretaker is a doctor named Crocus, who normally mans the Lighthouse that introduces travelers into Grand Line.

Recently, the only known survivor of the pirates that had abandoned him fifty years ago has been revealed to be Brook, an undead skeleton the Straw Hats met shortly before they arrived on Thriller Bark. He has currently reclaimed his shadow, so that he can exit the Florian Triangle, and return to Laboon.
