HAVE YOU EVER SEEN THE RARE ANIMAL CALLED THE SLION

This animal is rare at all. It lives in the imagination of every little child.

Some days ago, my niece came to me with a question; she asked, "Have you ever come across a slion?" and i answered her "Nope, i don't think i know what that is". "What is a slion" i asked. Then she answered, " if a snake marries a lion, their young would be called a SLION...

I don't think i want to ever come across such an animal... I cant even imagine which is gonna get the head, and which is getting the tail. Would such cross-breeding ever be possible?
