Hey, I'm rmo66xx. My favourite Thwomp is Dai Gorō. I actually don't really HAVE a favourite Mario Character... I also make art of Mario Characters, here, a mix between Grrrol and Dai Gorō if it gets accepted.
So, here's the thing. I'm not very good at editing things on this wiki, so I can only edit things like text. So don't expect me to help with pages anytime soon.
