You can gain infinite height in Metro Kingdom by abusing the Hat object. (This object is on a bench east of Pauline after achieving peace. It disappears once you collect moon No.57) You need to jump and immediately throw the Hat with Y, then dive towards the Hat and on the frame you bounce off of the Hat, press Y to pick it up followed by a second Y press to throw the Hat again and repeat the process. The Y press to pick up the Hat when bouncing on it is difficult and only has a window of about 2 frames.
