|“Bop till you drop, shake it till you break it. Move it till you lose it; spin it till you win it”|
|— Spin Harmony|
|First Appearance||The Royal Blacksmiths|
The Ninja formed Spin Harmony to replace The Royal Blacksmiths in a talent competition, so they could win the Blade Cup—a trophy that held the second Fangblade. Though they originally intended to sing (under Lou's influence), just before they went on stage it was decided that they do what they do best. The group ditched their "barber's quartet" outfits for their ZX suits, beginning to dance along to "The Weekend Whip." The Serpentine tried to interfere with their performance, but the Ninjas' Spinjitzu and cooperative fighting only made it more exciting to watch. Cole finished the performance by performing the Triple Tiger Sashay, which encouraged the judges to give a perfect score of 30.
