"Lady & Peebles" is the nineteenth episode of the fourth season of the American animated television series Adventure Time. The episode was written and storyboarded by Cole Sanchez and Rebecca Sugar, from a story by Patrick McHale, Kent Osborne, and Pendleton Ward. It originally aired on Cartoon Network on August 20, 2012. The episode guest stars George Takei as Ricardio. The series follows the adventures of Finn (voiced by Jeremy Shada), a human boy, and his best friend and adoptive brother Jake (voiced by John DiMaggio), a dog with magical powers to change shape and grow and shrink at will. In this episode, Princess Bubblegum (voiced by Hynden Walch) and Lady Rainicorn (voiced by Niki Yang) go searching for Finn and Jake, who have been missing for three weeks after fighting with the Ice King (voiced by Tom Kenny). It is reveled that Ricardio, the Ice King's living heart, has trapped them and wishes to marry Bubblegum. Bubblegum eventually defeats Ricardio in hand-to-hand combat, and saves the day. "Lady & Peebles" featured the return of Takei, who had previously voiced Ricardio in the first season episode, "Ricardio the Heart Guy". Several video games inspired elements of the episode, including The Legend of Zelda: Majora's Mask, Eternal Darkness: Sanity's Requiem and Amnesia: The Dark Descent. "Lady & Peebles" was watched by 2.754 million people and received largely positive critical attention, with Oliver Sava of The A.V. Club praising Takei's voice acting, and Richard Whittaker of The Austin Chronicle applauding the female-centric nature of the episode. The episode was later nominated for an Annie Award.
