Kevin Clash should make an appearance

[Shellington]

He is mainly known as the voice of Elmo on SESAME STREET, and had voiced Splinter in the 1990 TMNT film.


It'd be cool if he made a guest appearance on the show, though I don't know who he could voice.

He doesn't work much these days from what I understand, but I'd always welcome his return to the franchise. He's a talented guy, & his Splinter was amazing. They should get as many Henson-TMNT alumni as possible, even Sam Rockwell. It's great that we have Robbie & Corey as it is, though.
