It's the truth. Zebras are painted that way. This is an excerpt from the wikipedia article on 'List of animals in the bible.'
Zebras having painted stripes is a huge meme in the media. It's a big inside joke that has been around a long time. The "elite" of times past were in on the joke.
If you research images of people riding a zebra, most of the images are from around the victorian era. Then they started lying and saying zebra were too dangerous / untamable to ride. Which is clearly a lie. They very frequently say their hoax animals are deadly or very dangerous. It's to keep people from looking into it closely, because they will be afraid.
I already mentioned how zebras being painted that way is a huge meme in the media, and even in real life. In Tiajuana Mexico, for instance, they do a really bad job at painting sad looking donkeys up as "zebra" and let tourists take pictures with them. The thing about zebras is... It's all about passing. If the zebra paint job is horrible, it wont 'pass'. If you do a good enough job painting up a horse, then it can 'pass' as a zebra. By the way, it's not just painting that goes into making a zebra, they also trim the mane, and use rare / exotic breeds of horses.
The most obvious tells that zebras are painted that way are the faded stripes, and the fact they often don't paint the area right above the nose.
Fruit stripes is proud about being in on the secret.
