Cappy is Mario's companion in Super Mario Odyssey! 

In terms of voice, I'd like someone who can replicate something close to Cappy's voice in the game. It doesn't have to be exact but make it close so then it's noticeable.

This is also obvious, but I'm looking for a singer, not a voice actor. So you'll need to be able to hit those high notes and keep em there.

I'd like to keep the voice actor male, but if a female can pull off the voice while still sounding male, I'll allow it as well!
