Someone mentioned this link online and like most silly web games it has sucked me in. The idea of Grow is to drag certain materials onto this ball. As you drag more pieces on, the ones you have dragged on may evolve. As far as I can tell the goal is to max everything out. I'm doing okay so far, my score is around 10,000. Supposedly the max is 20,000. The damn propeller and tornado are driving me nuts.
