Animals are just like humans in the sense they can be born with abnormalities or differences to what's considered the norm.
There have been documented cases of conjoined species, albinism and strange colours.
Well, it appears there's been one of these abnormal animals growing up on a farm in South Australia.

South Australian stock agent Michael Foster was shocked when he saw a one horned sheep named Joey hanging around a property. It didn't take long before Joey was being called a unicorn because of where his solo horn was placed.
The sheep was all set for the slaughterhouse until Mr Foster stepped in.
Speaking to 7 News Adelaide, Michael said: "I thought it might have been a joke to start with, but I thought, 'yeah it looks like a unicorn. I've been a stock agent for about six years and it is definitely the first time I have come across anything like it.
"To the best of our knowledge, it is the only one in Australia."
It's reported the solo horn is due to a growth abnormality, which left the other horn underdeveloped.

But what's the standard asking price for a unicorn-sheep? Well, it seems as though Michael only had to give over two cases of beer to keep the special beast alive.
Joey is now enjoying life and soaking up the minor fame.
"We'll break him in, take him to shows and pageants, and who knows where we can go, maybe Hollywood," Mr Foster said.
"I'm sure the kids will get a big kick out of patting a real-life unicorn, we might even do unicorn rides."
If you like weird and wonderful animals then this one might be better than Joey - although this one isn't a rare fluke.
The Malabar Giant squirrel - double the size of its grey relatives and measuring up to 36 inches from head to tail - lives deep in the forests of India, so if you're wondering if you can get one for your office, chances are it might take a while to acclimatise.
The athletic animals can leap an incredible 20 feet between trees, which really puts it into perspective when you consider how self-satisfied you feel when managing to jump over a really big puddle.
Photographer Kaushik Vijayan, 39, snapped the animals in their native habit to produce these stunning images.
Kaushik, from Kerala State, India, said: "Up until that point I had never heard about a squirrel like that or seen one. The sight was an absolute feast for my eyes.
