A few tips for those going for 300, always start with the pop up rabbits because they take 3 individual clicks and you will often find the hidden teeth while clicking them. Silver teeth takes 3 clicks and gold take 5. You should leave silver and gold teeth for last because there is a small amount of time where the "mouth" is closed but you can still click them. Be patient, a misclick is far more costly than taking your time. Once you get to 200 the game really starts to become difficult, have fun!
