Favorite Toy DealsOutdoor toys for all ages

I vaguely remember seeing these stop motion short features on Nickelodeon (late 80s) where kids toy building blocks and maybe even toys were arranged into roads and things like that. There would be cars and other things made out of the building blocks driving down the little roads. It's killing that I can't figure it out, especially after recently rediscovering old shows like Adventures of the Little Koala, Pinwheel, Today's Special, Out of Control, etc. on YouTube. I hope somebody out there knows what I'm looking for!!
