These amazing Silly Squares are as fun to watch grow as they are to play with. Put them in a bowl of water and watch them grow up to 100 times larger! Use the included stacker tray to try to build with your Silly Squares. See how tall a tower you can build before it wiggles down! The kit comes complete with 5 different colors. Best of all, Wiggly Jiggly Silly Squares are reusable!
