Amanda

Amanda is a girl looking for her father's treasure in the second TV Special, along with her two siblings, younger sister Milia and baby brother Holy.

They stowed away on Captain Zap's ship but escaped along with Maccus and Bonney, eventually ending up on a deserted island where they meet Straw Hats. Their father was an adventurer who always brought them back gifts from his travel, but one day he returned home and died at their doorstep. However, before his death, he left a map etched on Amanda's back, which she hates him for at the start of the special. The map was what Bayan, her father's murderer, was after and forced her to reveal it through his pirate choir's singing. However, the Straw Hats managed to defeat Zap and Bayan, then help locate the treasure 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 Bonney offer to adopt Amanda and her siblings in the end.
