Carefully dodge the Reos to the left of the door leading to the Pink Hopper Room and lure them and the Sidehoppers close to each other. Place a Power Bomb to kill them and both Sidehoppers above. Go down below and lure the third Reo, below the Zeb pipe, off screen to the left. Overload PLMs by moving through the camera scroll blocks in front of the passageway leading to the exit of Spore Spawn Supers. Either carefully jump out of this morph tunnel or use a Power Bomb boost Spring Ball jump to get up to the ledge. Get into the Sidehopper pit and jump up and into the tunnel and go through the crumble blocks to the door to the left. Use a Power Bomb then quickly exit G-Mode before it explodes to also break the blocks.
