Crocodile Creek produce very high quality puzzles, even the pocket money sets are excellent and super value, some of the puzzles have fun pop up characters to assemble and the box can also be part of the fun.  The puzzles shown are just a small slection of the large range available.

 

The train and the jeep are actually the boxes for the puzzles shown below and can be played with on top on the puzzle when completed, how cool is that?
