What a pain this one was but many thanks to tylerh1701 on xbox360achievements.com for figuring this one out. He did it on Tilt mode, I simply did it on Touch on the normal difficulty.
Now what you'll want to do here is go to Level 43, "Warehouse" and from where you begin you will want to go into the room over you where you'll need to hit the wall on the right just over the crate. You'll die, whatever. So when you respawn you will go down into the room where you started. There, you will notice a wall missing on the left that was previously there. Enter. In this area, there are invisible walls over you so just stay low and skim over the 2 crates then hit the switch at the end. From there you can head back and complete the level, as though you would do normally EXCEPT this time DO NOT collect all the sun orbs. You can get them all but one as long as you don't have them all at the end of the level.
Once reaching the end, if you are still lacking orbs then the checkered finish line will still be red, except here you can pass through it into a vacant room above where in the top right corner, you'll see a double wall with the interior wall shaded out. Go there and hit the solid external wall. Boom. Enjoy.
Thanks again to tylerh1701.
