Thanks for the great suggestions, y'all. I only have room for a couple more...

There's only enough room on this wall for about 4 more, if that. Main contenders for the last bit are:

Lenny (the Simpsons), the Critic, muscle man (regular show), Enoch (over the garden wall), Totoro, Wakko (animaniacs), or, Mr. Anderson (Beavis & Butthead).

Thank you for all of the great suggestions on my previous post! That really helped me fill this mural out a lot. Have a good one, y'all.
