I did the meme again but with suggestions given to me on Twitter. The three characters on the bottom row are OCs of different friends so I guess I broke the rules here lol.

Top Row: Double D / Edd from Ed, Edd n Eddy, The Shadow , Professor Owl from (Melody/ Toot, Whistle, Plunk and Bloom and Disney's Sing-a-longs)
Bottom Row: Nicola belonging to Nikoalakuma ( https://twitter.com/NikoalaKuma ) , Ghostie belonging to PsiSnyder ( https://twitter.com/PsiSnyder10 ), SilviaStar belonging to Geeligan Stache ( https://twitter.com/GeeliganStache / https://twitter.com/GeeliganDraws )
