To summarize, then: when leveling up, first make sure all your trees are watered. Then, if you have persimmon trees plant 4 plots with wheat and the rest with vanilla. Have your friends give you 4 sugar and also have 16 bottles of milk ready to go. Use all of that to make scary cake. If you can't do those last two things, then just make witchin' batter instead, which can be made just from your persimmon trees, wheat, and six eggs.
