Who is "Antlers"

So I was messing around with Wido the Wild in multiplayer and when I went to player setup I noticed a character named "Antlers"
They aren't selectable from the character select screen as far as I can tell

They have no abilities (not even a spindash), all they can do is run and jump
They're just a silhouette except for their eyes and antlers
I know this kinda sounds like some weird creepypasta thing so I attached screenshots of them

I'm not sure if they're originally brown, they're just that color right now because I switched from Wido to them

Anybody know what this is? Some kind of hidden preview for a new character perhaps, or maybe an old scrapped version of Wido?
This question may have been asked before I'm not sure

on a second look I think it might be beta wido
IDK their running animation looks like wido's a lot

that's the extra details used on wido's super form
It's a separate skin overlaid over the super sprites

Ohhhhh, thank you. I never use super forms, so I would've never found that out
