What fictional creature do you wish were real?
After reading EWQ's answer, I have to agree. Anything that can do my housework for me is a must. I'm a little tempted by leprechauns, since they always have that cauldron 'o gold, take it away, and they have to have another one, right? having a leprechaun would be handy, because I can then afford to just pay someone to do my houseworkk, and I can pay for other things… I value versatility. Things that can do the same thing (to the same standard) and more should be more valuable than single-purpose things.
