Kill the first Sidehopper on entry. Standing in the doorway to kill it, using a Power Bomb, or jumping over it can work. It is required to avoid double hitting the ceiling Sidehopper with the Power Bomb, so lure it to the right, place a Power Bomb in the corner, roll over to lure the hopper and quickly roll back to Crystal Flash. In unlucky situations it is possible that the hopper only does small jumps and never hits Samus.

Place a Power Bomb on entry to kill the first Sidehopper, then cross to the left side of the room. It is required to avoid double hitting the ceiling Sidehopper with the Power Bomb, so lure it to the right, place a Power Bomb in the corner, roll over to lure the hopper and quickly roll back to Crystal Flash. In unlucky situations it is possible that the hopper only does small jumps and never hits Samus.

It is possible to cross all the spikes and avoid damaging the ceiling hopper with just Power Bombs. Place a Power Bomb at the edge of the runway then hold forward with precise timing to get a boost to skip the first two then have a small bounce over the third spike. The optimal starting position is on the second-to-last pixel of the ledge and press forward on the 1st, 3rd, or 5th frame which gives Samus a large horizontal boost. (On the last pixel, only the 1st and 3rd frames work, and further to the right only has at most one usable frame. Rolling into the bomb with momentum is not recommended and gives only a 1-frame window.)

Open the door, walk a safe distance into the doorway, and turn around. Wait for the Sidehopper to do 4 hops before beginning to shoot it. It can then be safely killed from inside the doorway. It is not recommended to moonwalk into the doorway, as this carries risk of shooting the Sidehopper pre-maturely. After bringing the second Hopper on camera, quickly get back to the right and crouch against the the ledge while aiming upward to safely kill it.

Shooting the Sidehopper delays its AI, which affects its RNG on later hops. If the Sidehopper is shot too early, it may do a short hop directly into the doorway. After the Sidehopper initiates its 4th hop (in which it will land on the ground in front of the ledge), it will be stuck in a safe pattern for long enough to kill it, regardless of whether it does large or small hops afterward.
