COI REFERENCE PICTURES
Mostly for their "cloaked," humanoid forms and the respective cloaking item used! Since there are so many large yokai species, there are cloaking items made specifically to reduce their size and make it easier to access buildings in the Hidden City. Leo was the first to find one in Big Mama's vault (during "Bug Busters"). It wasn't... on purpose, since he just saw bird and took it, but the surprise was useful all the same!
They're not super hard to get otherwise! Mikey and Raph just picked theirs up at a general shop in the Hidden City. Donnie's was the only one that cost much, but that was because he was picky. It's made blending into the crowd a lot easier.
