Wanda the Fish was a pirate and close friend of Cap'n Izzy No-Beard. She was captured by the Customs and Exise Office and found guilty of piracy, resulting in her immediate imprisonment in Rock Island Prison.
Rock Island Prison, a small detention facility off the eastern coast of Karamja, proved to be inescapable for Wanda, who eventually died within her cell. Customs buried her body and placed her belongings and documents in the prison's locker office.
Her close friend, Cap'n Izzy No-Beard of Brimhaven, was devastated by her imprisonment and death. During Rocking Out, Izzy asks the player to retrieve her brooch from the heavily guarded lockers. Once the player gets the brooch for Izzy, he keeps it to remember her.
- Wanda the Fish's name is a reference to the 1988 film A Fish Called Wanda.
