This one isn't hard but is challenging. On the second to last cematry level you will need to collect tokens to unlock the grim reapers gate. When you are going for the blue one you won't be able to get it until you beat the Leprechaun in a race. You just need to go through the rings. It will take you a couple of trys before you beat him but you will eventually do it. He will try to push you so try to stay away from him and remember to jump. You need to be in front of him by 3 seconds.
