I had a whole bunch of Playmobile that I bought for my oldest Grandson years ago. After he was done playing with it, outdoors most of the time, it got packed away for 4 or 5 years. I sold it all last year. It was very sturdy and could take a lot of good hits without breaking anything. We ran it alongside a few LGB models I had back then. The LGB were fragile compared to the Playmobile.
I just saw it mentioned above as still being available. I don't know when the last time was I saw any of it for sale at a store. Sure was "kid friendly" though.
