Well, I didn't see those frames in Ridge's sheet, so I thought normal Cell Goombas don't have that pose :/

Well, they seem to have mostly the same sprites, so I thought that the feet needed would be in the tiles.

...However, just to make sure, where would I find those Shelled Cell Goombas in the game? They would be somewhere inside Bowser, right?

Yeah, inside Bowser, but they are a boss. Do you want the save state? :/
