A card in a box doesn't have to be square. It can be any shape with an even number of sides.
This pop up daisy card has six sides. Some of the insects and butterflies are glued to the interior props and some are supported by strips of acetate. The top flaps are cut in petal shapes to resemble a daisy when it is open.
