Or Are They

I know the Gangreen Gang are based on the Cosby kids as if they are created by Ed Roth and they do look like Halloween monsters but have ever consider they might look like types of reptiles and amphibians? I always thought they were born green.
Ace=Cobra
Snake= Python
Arturo=Iguana/Gecko
Grubber=Frog/Turtle
Big Billy=Turtle/Frog
That's just my guess.
