Explanation: For some reason, when you walk towards a candle, you will clip through the inbounds wall. Walk into the corner as shown in the video, then turn around VERY quick to not go too far away from the candle, go into the spinjump-formation and immediately press B. Luigi should be in the corner now (not shown in the video unfortunately). Now "wiggle" downwards and hope you will clip through. If you are up, but Luigi doesn't want to clip through as well, then you probably walked too far away from the caldle. When both are OoB, just walk to the right pipe (the left one skips way less).

                For the second skip, all you have to do is drill into the flamethrower. For some reason, Alphadream put checkpoints on the 
                platforms. By drilling into the flamethrower you hit the checkpoint. Now fall into the lava to get behind the flamethrower.
                Now you just repeat this two times. After getting hit by a flamethrower, either use the drill to get to the lava without hitting 
                another checkpoint or use the spinjump, both should work.

IMPORTANT: Avoid the red marked area (not 100% exact)... ...when you want to fall into the lava, or you will hit the checkpoint. This can easily be avoided by using the Spinjump.

Time saved: about 50 minutes (Yes, this place it loooong)
