Do you hear these croakings from the amphibians in our Cute Frogs Sticker? We suppose it's a frog family with a weird tradition of making a tower of themselves, standing one on another, on every significant occasion or a big event. For example, today is the big day because you are here, and these green frogs are glad to see you. Or maybe they are spies on a secret mission to save the world by building a tower of themselves.
