Maybe the color blue and purple have to do with age? Ever think about that? But the scrubs in Munch were brown or grey. Well thats because they had dirt all over them which made them appear like that. Thats my guess. They had to clean up sloggie poo. A green Mudokin I figure would be much younger than Abe and as they get older their colar changes to blue then purple then white or grey. Thats what my theory is. Ya Know?
But dident Alf explane why Abe was blue? I think he did.
