Either kill the Sidehoppers immediately on entry by placing a Power Bomb while rolling off the stair or tank their hits. If Samus has Morph Ball, it is also possible to kill the Sidehoppers upon room entry with Screw Attack or a powerful beam. Overload the PLMs by rolling through the camera scroll blocks which are 4 tiles to the right of the stair by the door. Roll under the last Sidehopper and through the bomb blocks.
