4-Castle (NSMB)

The level 4-castle is the fourth castle in New Super Mario Bros, as well as the place where Mega Goomba is dueled. Not far from the start, Thwomps appear, but first, there are a few swinging platforms. A Star Coin is obtained if Mario or Luigi hops at the highest point of one of the platforms. After a few more swinging platforms and Thwomps, a Super Thwomp appears. After running past this large Thwomp and stomping a few Dry Bones, Thwomps and a Podoboo will attempt to stop the plumbers from getting on the next set of swinging platforms. Podoboos jump from under. After going past several more platforms, Mario and Luigi will duel Mega Goomba and proceed to World 5.
