"When you entered Einstein's lab you saw that brain you've been looking for so long. You almost had it, but you accidentally knocked down a radioactive chemical that spilled on you, and all over the floor. All of the sudden you are beginning to get smaller and smaller until you are only about as tall as a pinky. Oh, and look out at that, there's a jet pack lying on the floor. Pick it up and get on your way to Einstein's brain. You only have eight lives, so watch out for the chemical that's still on the floor."
