This is Niftski's WR run of Any%. Flagpole glitch can save time if your going for a WR speedrun. If you already know how to do flagpole glitch in the original SMB1, It should be a piece of cake to pull it off as FPG is basically the same as in SMB1 in Petscop. But if you don't know how to do FPG. It will take time to practice FPG. Go to 0:26 in the video to see Niftski's FPG. Again, almost the same thing as SMB1 FPG.
