Epic Cho'Gath Skin Idea
Here comes Mrs. Chogath!

This would really work as an Arcade theme for chogath (Pacman / Mrs Pacman anyone). It gives a nod to the era of arcade gaming and considering how chogath gets stronger when he eats things, I feel that kind of hearkens a little to the pac man games. Considering it references one of the classic series, I can't help but suggest it.
I mean just imaging hitting your ult with cho and hearing a bleep bloop bloop bleep as you grow in size. His E spikes could easily be turned into an arcade theme particle. And I'm sure interesting stuff could be done with his scream and knock up.
