Why don't we build a topsy-turvy tower out of cups? Peek & Stack by Alex Toys features 4 funky stackable cups to pile on top of each other, each with a silly pattern! Find an animal hiding on one, and put a ball in the smallest one when you reach the top! If you knock over the Peek & Stack toy, just start again, and practice your motor skills. Play with the stacking toy and learn coordination while having fun! From Educational Toys Planet, Peek & Stack is great for playing, building and learning!
