I had an alien one back in the day...my little sister gave it to me after she had gotten tired of it. I was a teenager at the time, but I thought it was amusing. I brought it to work with me, and everyone I worked with took turns 'babysitting' it...full grown adults feeding my little alien baby and cleaning up after it...I don't remember how long we kept it alive, like almost a month, if memory serves. Thanks for the walk down memory lane!
