Words fail me. This is up with the fruit and the sushi
I found mine. These are from the second run in about 1990, they transform into dinosaurs. The first lot were better, they opened up and had robotic faces and arms that popped out. I'm sure someone posted the advert that McDonald's ran for the first lot.
i have the humanoid robots except the egg mc muffin the soda cup robots and the container one from the first series i also need the rest of the dinosaur robots i have the happy meal container one the chicken mc nuggets and the fry one
I had one possibly from Australia as I lived there for a while as a kid which was a Hot Cakes box which transformed into a pterodactyl type thing. It was almost certainly part of this series as I had the burger and fries too
