First Moon Skip

First moon skip (known more commonly as FMS) is a strategy used in 1.0.0 speedruns of the game as if you perform FMS in any other versions, the madame broode fight will not trigger. FMS saves roughly 13 seconds if done optimally. In 1.0.0 speedruns, FMS is one of the most difficult tricks in the run. There are two types of FMS

Rock FMS

Rock FMS is the first type of FMS to be discovered. It is the most difficult of the two and saves the least amount of time. Here is a clip of rock FMS being completed https://twitter.com/gamenerd607/status/1176054509799235585. To perform rock FMS

Jump on top of the rock that is surrounding the 'Our First Power Moon' moon

Throw cappy

Perform a cappy roll jump

Wet FMS

Wet FMS is an easier and more optimal method to skip the first moon. It is best explained by smallant1 in this video https://www.youtube.com/watch?v=f8Qr8UK5yZc&feature=youtu.be&a=. To perform wet FMS
