Tower of the Wing Cap

The Tower of the Wing Cap is a castle tower in the sky that contains the Wing Cap's ! Switch. Upon entering the level, Mario will be granted with a Wing Cap which he can use to fly around with. Upon landing on the tower, Mario will be able to press the Red ! Switch, which in turn will make all the Red ! Blocks solid. A Power Star can also be found here.

In Super Mario 64 DS the area was simply retitled '''? Switch''', and only Mario was granted with wings upon entering (the other characters couldn't fly and merely dropped out of the level). The ! Switch was also changed to the ? Switch, which activated all of the ? Blocks in the game. However, the feel of the level more or less stayed the same.

The entrance is located on the first floor of castle. Once Mario has collected 10 Power Stars (14 in SM64 DS), sunlight will be shining down from the ceiling. If Mario stands in the sunlight and looks up, he will be transported to the level.

Although the sunlight will disappear once the ? Switch is pressed, Mario can still return to the level by standing in the same spot and looking up.

Star 1
Using the wings that he is granted upon entering the level, Mario must fly around the area and collect the eight Red Coins floating in the air in the four compass directions. The Red Coins are found in groups of two. Due to the fact that Mario slowly loses altitude while flying, he'll have to reenter the level and try again if he drops below the point the coins are at.

Trivia

 * Before being transported to the course one can briefly see in the ceiling the picture of a blue sky with a white Sun. This same picture is seen on the second floor in normal paintings that Mario can't enter.
 * The tower the Sand Bird flies around vaguely resembles the Tower of the Wing Cap, due to a similar layout.
 * Noki Bay in Super Mario Sunshine is accessed in a similar way; by standing on a similar pattern on the streets of Delfino Plaza and staring up at the real sun.
