Climbing the room and remaining at the top has a very high risk of getting hit by a Waver. Quickly move to the right and exit G-mode to fix the camera. It is possible to kill the Wavers off-screen with one or two Power Bombs or a blue suit; Screw Attack is also relatively safe. Without any of those, it is best to roll to the right without unmorphing, and requires a bit of luck.
