Maybe not that obscure but we’ll see
All I can remember was that I saw it in the mid-eighties (?), it had a Moebius feel to it and unfortunately the only part of the actual cartoon I can remember was some sort of kid, hiding in a massive, pale grey, broccoli looking tree that was located in a desert with a few other broccoli trees dotted around.
I also seem to remember something (animal maybe) flying around looking to rescue the kid.
Anyone got any idea? It’s been bugging me for ages now
