Tank the Sidehopper hits or kill them after a single hit by quickly placing a Power Bomb. It is also possible to kill the Sidehoppers with a very fast Screw Attack, if Samus has Morph Ball. 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. Place a Power Bomb next to the right wall then quickly exit G-mode before it explodes to destroy the blocks.
