In the top left is K.Z. O’Neil. Next to him is some sort of shapeshifting horror. Next to that is a light sketch of Moe.
Slightly below K.Z. is an unfinished sketch of a shotgun. Beside that is a more civilized version of the chimpanzee mad scientist from yesterday. And then it Moe again.
The final four heads (ignoring the very light sketch of Detritus on the right) are Lili, an older gentleman (probably some evil bureaucrat from King Roach), Detritus and, finally, a random mutant.
