Marty Oppenheimer School of Performing Arts is a school that is mentioned in the episode The Royal Blacksmiths. The school is located in an undefined part of Ninjago City.


Cole was once a student at the Marty Oppenheimer School of Performing Arts, though due to his failure of the Triple Tiger Sashay when he was seven, he ran away. In the episode The Royal Blacksmiths, Cole recalls that the first prize for the annual talent competition is the Blade Cup, which is actually a Fangblade. All four Ninja dress in casual attire and arrive at Lou's house with the intentions of stealing the Fangblade. Because Cole had been lying to his father about attending the school, he told the Ninja to act as though he was still a student there. While referring to the school however, Jay calls it the "Martha Oppenheimer" by mistake, only to be corrected by Zane shortly after.
