Charge Beam Escape Clip
When coming from Waterway Energy Tank Room in such categories as 100%, you are able to clip through the bomb block above the charge beam item instead of destroying it. This is a 3 step clip. First, run and jump holding down to stand upright on top of the bomb block. Second, jump and press down and then press forward. This will get your foot stuck in the top of the block. Third, jump to perform the clip.
