My first thought was that it might aid in draining them as an air hole, to stop it from going glub blub, especially if they contained something really viscous like honey or oil, but then why not just one air hole, and why not higher up?
My second thought was that maybe someone just intended to make them look like faces for some reason.
Why do you think someone would go to the trouble of drilling 2 extra holes in each of these containers?
That’s a good question! I am also interested.

I’m going for b)
in/out hydroponic pipe feeds and the original hole to top it up? But there’s a lot of them.
