It’s an advert for a random “stay awake” chemical.

At the top of the image it says “fight sleep” which is to imply that by taking, whatever it is, you can fight off sleep, and in this instance, the counting sheep that you’re supposed to do before sleep.

Whereby the ad is supposed to make you think that it helps you beat up the sheep in your head, so you can stay awake longer.
