*You are a fish. Your goal in life is to be free of the big nasty shark that is always chasing you. After many months of scheming, you finally have a plan that just might work.
*Now, the ocean that you live in has two kinds of bubbles: good and bad. Good bubbles are colored green and give nourishment to whoever pops them. Bad bubbles are colored red and make you sick.
*The shark is not very smart, so you think that you can trick him into popping enough bad bubbles that he gets too sick to chase you.
*The trick is getting him to pop only bad bubbles while you only pop good ones, all the while staying out of his reach.

Good Luck!
