Like... Fire things, green things, bed things, playing things and hundreds of other things. Love it almost as much as animals that are just something-animal. Like bag-animal (marsupial), beak-animal (platypus) or belt-animal (armadillo).
I think it's fun how Zeug has gone from a technical meaning to a cute one.
The current meaning of Zeug is something like stuff or unimportant things.
It used to mean kit, gear or equipment though, which makes a lot of sense and is still visible in words like Zeugwart (equipment manager of a sports team or army).
With that knowledge, Werkzeug would just be a tool kit.
Same thing in Norwegian with "tøy" (verktøy, fly, kjøretøy, plus fartøy for water-faring vessels) … and then tøy by itself means cloth or clothes (also available through klestøy)
