Ok 1st go to either tower in haven city and look arond for a pipe on the bottom that looks like a c, next when u find it jump up to a nother pipe then look for a biger pipe jump up to it and when u get to a edge go around do the same thing over again but next time there will be 4 platfoms. on 2 of the platforms(this is for both towers) ther is a lot of boxes break them and on each platform ther should be 2 eggs on each side there should be power lines grind on them there are a lot of eggs its not exactly 20 but there was one egg i couldnt get.
