USB keys are getting wackier and wackier and this Piranha Plant USB Key is on the top of my list of ones to buy. The minimalistic USB key sports a circuit board design with the addition of the classic Super Mario Brothers villain we all recognize from our childhood.
Probably the funnest part of this Piranha Plant USB Key is the fact that a little LED bulb lights up whenever you plug it into a computer, emulating the classic Mario villain's trademark attack. It's available in keychains, necklaces, earrings and magnet designs, and to top it all off, it only costs $5 on Etsy!
One minor problem though, is this thing doesn't actually store data. But that's okay because I have tons of other fun-themed USB keys that can do that job anyway.
