Aside from the lack of buttons, this is Mr. Bill! Do an image search. Oh how I miss old SNL.

*Copepod* Sorry - hard core science geek here has to see it spelled correctly.

This looks like a simple case of cycloipa or holoprosencephaly, with a median eye (2 irises) and the proboscis/snout above the eye. This same thing happens to humans and other mammals. This piglet has nothing to do with a primate and is 100% piggy. This is most likely a result of a chromosomal disorder during gamete formation. Doing an image search for cyclopia will yield some interesting and similar (yet graphic) results, including the two irisis in one median eye.
