|“You can't! He thinks I'm in Ninjago City training at the Marty Oppenheimer School of Performing Arts. He wanted me to follow in his footsteps. But when I couldn't sing or dance, well I...I ran away.”|
|— Cole to ninja about his father, "The Royal Blacksmiths"|
The Marty Oppenheimer School of Performing Arts is a school located in an undefined part of Ninjago City.
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.
Zane mentions that Cole went here while trying to convince the latter to sing.
- According to Cole's LEGO.com description for Rebooted, he only attended this school for two days before running away. However, this may not be canon.
