Two-faced piggy

Back in July, I wrote about a kitten born in Ohio with two faces. Recently, a pig was born in China with a similar mutation.


I wonder just how common such mutations are?

This little piggy went to market,
This little piggy stayed home,
This little piggy had roast beef,
and this little piggy had strontium-90 and radium-226.

Hmmm... I wonder if this mutant has any superpowers?
