3D Dynamic Puzzle

short video clip of a toy forklift

I'm surprised that Colin could assemble these types of puzzles on his own. Supposedly, the puzzle is recommended for age 8+.
I would thought he needed help but he didn't want any assistance.
He assembled the paper Forklift, well most of it except some nook & cranny where he couldn't get the tabs to fit into the slits. For those areas, he taped them up with masking tape.
Good try, problem solved.
