>>48902683Natch'. Don't try looking for one though. I made mine with what little sciencey knowledge I have.
It's an actual potato battery with her eye, which I fashioned out of various parts instead of a normal small lightbulb. Then I stuck a speaker and some bits from a dodgy mp3 player and actual alarm clock inside it... Well, it's a little more technical than that but you get the idea. The only problem is that I have to replace the actual potato every now and then or it starts to smell.
