If you often forget to close your fridge door then you need Hogen the polar bear.
This polar bear is a fridge alarm. Just put him inside your fridge and then when you open the door Hogen will start talking to you so that you know that the door is open.
And to make it a bit more fun this polar bear only speaks Japanese and that of course will make you smile overtime you open the fridge.
Maybe you wonder what it says but I don’t think it will complain about the cold as it is a polar bear.
Come check out this Polar Bear Fridge Alarm.
