Click the ball to make it change colors

Bring it to the top left corner, then move your cursor off the game screen. Bring the cursor right next to the ball along the left side of the game screen. Quickly move the cursor to the right onto the ball and click. You should be able to get it almost every time.

The Carnivore way is easy cheesy. Honestly, within a minute or so you should be able to get the hang of a gentle tug up to bounce it right to your pointer for a quick point.

Or maybe my mouse is just "special."
