Go to the Kona level and go over to the guy that wants you to get the birds off of the powerline. When you do it drop down the halfpipe and go above the powerline. While you're above the powerline do a 900. Since you can't fully land a 900 you'll hit the powerline and get electricuted. You'll turn black and as you get up you will look like you're about to change back to normal, but instaed you'll change into a zombie.When your a zombie you half to go and land 1 trick and when you do you'll unlock all levels and get every single one of your stat points all the way up. Once you've done that you half to do another trick, but this time you'll have to fall. When you fall your head comes off and then a ghost will come out of the head. Once you've changed into a ghost go into some grass and then fall again. You'll sink into it and then the whole level will change into a graveyard. You better make sure you save this because it can be really, really hard to do sometimes. This cheat really works. All of my friends have tried it and they were very successful in doing it.
