Aww, remember The Puffin Club, readers of a certain age?
I used to wait with baited breath for the next issue (once a term I think, when one of my teachers would get a copy from another teacher friend... rationed by cash and good old fashioned "you can't have all of them" training by my parents (yes folks, kids DIDN'T get everything they wanted in the late 70's/80s), I was allowed one book an issue... After my beloved moomins, this was one of my hunkered for yet never attained choices.
I happened upon this in a charity shop in Devon last year, and just dipped in - I'm not disappointed! Nice little tale of good, bad & giggly; it's a bit like the wombles , but in the outback. Published 1967 themes of recycling, keeping the countryside clean and taking your responsibilities seriously, but working with friends or as a team... topics that don't go out of fashion in a nice tale for young children
