Wow-o-wow it's a pile of crocodiles! This set of 5 or 10 little acro — er, crocobats are designed to nest and stack to build a tower of friendly crocs. Get snappy and use their mouths as cantilevers or simply interlock the notches on their backs. Need a bigger challenge? Add multiple sets to create a tall croc tower. After a while, you'll be a crocodile stacking pro.
