How do you beat Megaleg in Super Mario Galaxy?

Answer 1

well first of all wait until his 3 legs are down. Then you'll see a a latform with green arrows jump on in then it turns red. (red means warning) then you Dodge the bullet bills then youll see a gate with the grand star in it lure a bullet bill to destroy it now another gate pops up without a ceiling and it moves now this part could be challenging. Ok now you lure a bullet bill to destroy it. *its hard to lure the bullet bill on the moving gate*
