There is a crazy scientist who is testing chemicals to give humans the magical ability to fly! He has gotten so insane that to test it out, he tried it out in you first! Good thing it wasn't fatal. But, instead of giving you the power to fly, the chemical has shrunk you! The cure is to get all the stars and get to the green goal. On your way, free the tiny bird who the scientist has trapped and has tortured to understand flying. Free the bird, and the bird will give you a star, one of the stars you need for the cure. Good luck!
