Fluffy Bluff 1
Advanced
0:00 - Optimally, Fluffy Bluff 1 is done after the Secret Mission, so cutscenes can be skipped for RTA Simulation.
0:07 - Jumping to the very edge of the Cloud Flower platform will make it easy to avoid the coin.
0:15 - Avoid Long Jumping from the edge of the cloud, as you won't get a boost from it.
0:26 - These fountains will be active when you arrive if you do Fluffy Bluff S before Fluffy Bluff 1. They are easy to avoid by landing the Long Jump far enough to the right.
0:35 - This sideflip is quite risky but not as precise as it looks; keep running forward until Mario starts to slow down, then immediately switch the control stick to Down+slightly to the side, and press A simultaneously. Alternatively, you can start off by running forward and slightly to the side, then switch to just straight Down for the sideflip (as seen in this example).
0:37 - This Cloud-Boosted Long Jump must be strained quite a bit to avoid bonking on the mountain.
