Fridgeezoo Fridge Pets. €19

Assuming you are old enough to have moved out of home, it’s probably been a while since your parents chastised you for leaving the fridge door ajar.

In its stead is the Fridgeezoo Fridge Pet, an electronic animal shaped like a milk carton that will spout phrases in Japanese when you open the fridge door.

Activated by a light sensor on the top of the device, the animals will remind you that the fridge is open, ensuring that you can’t walk away and forget about it, thereby wasting electricity and possibly spoiling your food into the bargain.

The devices are available as a penguin, pig, tiger and walrus. You may also learn some Japanese into the bargain. firebox.com
