Find Out What’s Wrong With This Image With Zebras

A normal picture of zebras taking advantage of some free time to have something to drink right? Ok, I know zebras have always a free time as they don’t have to go to the work, you would wonder how occupied they can be sometimes. They don’t live in the safest place on earth at all and actually spend a lot of time escaping from a random predator that happens to come by. Don’t forget that they also have to find some time to eat and do some stuff around the family (no, they don’t have to do dish washing haha) Anyway, just look at the picture and tell us what you think is wrong with that image. This one is really easy in my opinion. I would also appreciate if you tell me if you like this type of riddles or which one do you prefer most.
