OK, so maybe you didn't actually realise what was missing from your life, but now you've seen this eco-friendly glowing rodent*, you're all going to sleep easier at night knowing it exists in the universe. According to Abi over on Hippyshopper, it's eco-friendly, using LEDs and the power of squeeze technology to set the bat aglow. Just the thing for Hallowe'en.

*Yes, I know it's not really a rodent, but "glowing Megachiroptera" didn't have quite the same ring to it.
