Papier-Mache Pull Toys. I wish I knew about this when my child was little. Get everything needed from a crafts store : Paper mache animal, glue, bloc of wood, 4 wheels, 4 wheel pin, paint, and rope/cord. If needed one could even get a craft tool to drill the hole with at the store or use what you have. Would be cute to do circus cars (sting a few together) train as well.
