Inverted Pyramid Skip
Inverted Pyramid Skip (often shortened to IP Skip or Pyramid Skip) is a trick that allows the entire interior of the Inverted Pyramid in the Sand Kingdom to be skipped. It involves scaling the outside of the pyramid up to the exterior of the 2D section, then performing a difficult midair corner clip to clip out of bounds in order to climb all the way to the top.
Because the Hariet boss fight at the top of the pyramid will trigger before collecting either of the previous two Story Moons, this trick can be performed before even completing any other story objectives in the kingdom. It is a faster alternative to Inverted Pyramid Clip.
