Sonic The Sorcery Hedgehog (The Voodoo Teletubbies Sonic Shuffle)

Official Sonic The Slenderhog Popups (The other two images I can't make because the text in "Your Next" does not need to be swapped and I don't have a Green Hill Zone map to put Amy and Cream in for the other one).

Official Crash Slendercoot model (Crash Slender Ponies style)

Tubby Teeter Explained (Most of the art is not mine) (I don't even own the characters on the top)
