The Secret Of Battle Fort

The Secret Of Battle Fort (or Battle Fort) is a secret level in Super Mario 64 DS, in the back of the castle, in the courtyard, with the boos. Under the three brick blocks. Because Yoshi cannot destroy them, a mustached hero must enter instead. To track the star down here, you must get 5 silver stars. There's a lots of obstacles, like Chuckya, Black Rolling Balls, and many others, so be careful.

Trivia: It's the fourth and last course in multiplayer VS. Mode, and was titled Battle Fort, and the only hazard that has remained is the black rolling balls.
