The tricky part is getting to the ledge below the missiles. There are two ways to do this: 1. Stand on a frozen crab with a frozen fish at the lowest height of its cycle to the right. Further to the right is better as long as it can be stood upon without the ledge above. Perform a stationary lateral midair morph into a max height spring ball jump to get onto the fish before it thaws. Press against the fish for the maximum amount of time possible while moving upwards in order to gain more height in order to get on top of it. 2. Freeze the global crab on the right wall, get onto it and up and onto the frozen fish before it thaws. Be careful not to fall through the crab. A fail will require Samus to reset the room, or wait a very long time in order for the crab to circle the room. Using a Super may make the crab fall on a floating platform, and it still takes more than a minute to return. Note that it is possible to turn off ice beam to immediately thaw any frozen enemies; this can help get the crab and fish in a good cycle with each other.
