For some people, it's the little things that matter most. For example, if you've ever lived in a house with someone who would always get on your case about leaving the refrigerator door open for too long, you know that every drop of energy matters. If you've moved away from that person, but you want to make sure that you're not wasting any energy by leaving the fridge door open for too long, then perhaps the Fridgeezoo Animals should be something you look into.
Simple enough in their design, it wouldn't be too far of a leap to suggest that they're cute, too. Designed to look like animals that live in colder climates, you'll find a peguin, walrus, seal, and polar bear waiting for you every time you open the refrigerator. Every time you do open the door, they'll be happy to greet you and say nice things, but everything changes when you leave the door open for too long. They'll quickly turn nasty, telling you how much energy you're wasting.
If you've ever heard of the Japanese hip-hop crew Romancrew, then the voices of the animals will sound familiar enough. You'll be able to get one of your own for about $25 each, or 1,980 yen. They're available right now in the Appare Store, if you're trying to find ways to make sure that you save energy every way that you can.
