We should call "Platypus" the people with down syndrome, why?
- It's clearly a mistake in the evolution chain, not even immune to its own poison
- He never manages to hit the only hole in the female
- The face is a reminder of that syndrome.
- He is bullied by other animals
- He sees animals moving, but not dead ones, so he is at a disadvantage
- When he walks he looks like a mongoloid
- When they first saw them they thought it was a mistake of nature, and indeed it is.

>>> The platypus is perfectly comparable to a boy with down syndrome
