Feast your eyes (and ears) on Fridgezoo, little milk-carton shaped animals that cheerfully greet you as you open your refrigerator door.
Should you leave the door ajar for too long, though, these little box things will squeal again, asking you if you want to close the door or not. Check it out:
There are 4 varieties of these little boxes: penguin, walrus, seal, polar bear. Of course, these are limited to cold-weather animals because, of course, they live in the fridge. Cute!
