Wishing Liquid

I am clearly having too much fun with my hygenie. I'm in the process of mocking up a picture of the hygenie and I've discovered two things:

1. He lives in a bucket. Y'know, instead of a lamp.
2. The number of wishes he can grant is proportional to the amount of wishing liquid he has in his bucket. Insert pun about wishing liquid/washing up liquid. When you get the hygenie, the bucket fills with wishing liquid. And it can spill and stuff. If you want a bigger thing cleaned, it takes up more of the wishing liquid. Smaller things = less wishing liquid used. Then when you run out of wishing liquid the hygenie goes away. =(
