This is harder when crossing the room and easier if the left door can be used to reset the room, but it will cost one extra Power Bomb. Place a Power Bomb near the first and third bomb walls. One Waver will be alive by the fifth wall, which will only move while on camera. Get it to move to the right in order to safely Power Bomb the final set of walls. Follow the Waver around the room a few times in order to get it to the left doorway.
