If there are no Sidehoppers in the bottom right corner of their pen, roll down and carefully place bombs while luring and killing them. Otherwise, go down into the hallway below and carefully kill the two Reos and lure the Sidehoppers to the left. If they don't stay on the left, exit this hallway and enter it again to reset the camera and try again. Go up through the crumble blocks to the left. If PLMs are not yet overloaded, place Bombs next to the crumble blocks. Use a Power Bomb then quickly exit G-Mode before it explodes to also break the blocks.
