Amanda

Amanda is a girl looking for her father's treasure in the second TV Special, along with her two siblings, younger sister Millia and baby brother Honre, during which they stowed away on Captain Zap's ship but escaped along with Max and Bonnie, eventually ending up on a deserted island where they meet Straw Hats. Their father was an adventurer who alway brought them back gifts from his travel, but one day he returned home and died at their doorstep. But not before leaving a map etched on Amanda's back to which she hates him for it at the start of the special. The map was what Bayan, her father's murderer, was after and forced her to reveal it through the his pirate chours's singing. However the Straw Hats manages to defeat Zap and Bayan then help locate the treasue which turns out to be a gigantic clam and pearl (i.e: the island they were on). This regains Amanda's respect for her father while Max and Bonnie offer to adopt Amanda and her sibling in the end.
