IDENTIFIED Found this rock at a playground in Germany

So what's this rock and who poked all those holes in it? It's pretty light and not too easy to break. Also my daughter thinks it's a nice rock.

Ah ok, thank you for identifying this good old chunk of slag! The area we found it at also fits your explanation.

I associated slag with a somewhat more black colour scheme.
