Our 100pc puzzle is made up of 3 separate puzzles that all integrate into 1. There are 2 x 12pc larger puzzles that then attach onto the main 76pc puzzle. Our Happy Hospitals design has a brilliant big helicopter and a large, super cool ambulance to find and make, they then slot into our gorgeous Happy Hospital scene. Once your puzzle is complete, you can pop it all straight back into the fabulous high quality attach case (featuring a beautifully illustrated lid) and take it onto your next adventure using the brightly coloured handle - so much fun!
