These lenticular puzzles will be enjoyable to assemble and even more fun to look at once finished. Unlike other puzzles, the ones in this collection have an added touch of uniqueness in how they change depending on your angle of view. These different puzzles require enough of a challenge for children to put together and they can also have great satisfaction in seeing the design of their creation shift right in front of them. Kids will be able to see unicorns move and fly, animals transform, and more as there are three distinct changing designs that can be viewed for each puzzle. Each of these lenticular puzzles include 75 pieces and measure 17.75” x 11”.
