The Galoobie Ruby is a valuable gem that appears in the 1987-1996 series episode Polly Wanna Pizza. Approximately fifteen years before the events of the episode, it was stolen by Mugsy McGuffin and hidden in a safe at the Bering Arms Hotel. The key to the safe, and thus to the ruby, was placed around the neck of McGuffin's pet parrot Polly.
However, just as McGuffin was released from prison, the Bering Arms Hotel was due to be demolished. Michelangelo's arrival shortly before the building was set to explode caused the safe to fall several stories. After he was rescued by Polly and the other Turtles,the explosives were set off, shattering the Galoobie Ruby into dust.
