- Stand on the higher of the two vertical platforms near the exit of the long Morph Ball puzzle. Then, do a Space Jump followed by a mid-air morph. If you time it right you should make it over the grating and skip the puzzle. You don't need Spider Ball to do this.
- A well brandished BSJ from the wall opposite the grating followed by a mid-air morph can also be used. Vid (outside link)
