I loved Thomas the Tank Engine (Thomas toget in norwegian)
I don't know what the boat is called, but we have a norwegian equivalent or spinoff which is called "Elias".
My favourite was definetly the Transformers. I think I can still remember just about all the dialogue from Transformers: The Movie, also from 1986 like the pony movie. It could perhaps deserve a proper mention in this thread, but I don't think it's actually underrated!
