Full Walkthrough: http://www.gamefront.com/little-big-planet-2-walkthrough/
This is pretty much just a standard side scrolling shooter level on top of a giant camel that shoots lasers out of its mouth.
Move the cursor with the left stick and fire with "X" or "R1″. If you want to fire really fast, try mashing both of the buttons at the same time.
Pretty much all you need to know for this level is shoot everything. There are plenty of prize bubbles to find along the way, but none of them are particularly hidden.
NOTE: As tempting as it may be, don't shoot Avalon. Everytime you shoot him you will lose 10 points.
Once you reach the boss at the end, just shoot its eye whenever its exposed. Typically he'll put his hand over it after two or three shots. While he's covering his eye, focus on destroy the various missiles and bombs he sends your way.
Once you defeat the boss, you'll reach the end of the level
