Tower of the Wing Cap

The Tower of the Wing Cap, called the Wing Cap Course in the original message that appears upon the player entering and the Wing Cap Tower in Australia's Nintendo Magazine System, and simply labeled '''? Switch' in the DS remake (although "Tower of the Wing Cap" was still in use by Prima Games), is a castle tower in the sky that contains the Wing Cap Switch, appearing in Super Mario 64 and Super Mario 64 DS''. The entrance is located on the first floor of the Mushroom Castle. Once the player has collected ten Power Stars (14 in Super Mario 64 DS), sunlight will be shining down from the ceiling onto the rug in the center of the room. If Mario stands in the sunlight and looks up, he will be transported to the level. The cloud pattern on the ceiling can also be seen on the second floor in normal paintings that Mario cannot enter, and even later in the entrance holes of Rainbow Ride and Wing Mario Over the Rainbow. Although the sunlight disappears once the red switch has been activated, Mario can still return to the level by standing in the same spot and looking up.

Layout
In Super Mario 64, Mario immediately appears in flight as Wing Mario. Upon landing on the tower, Mario is able to press the Wing Cap Switch, which in turn makes all the red blocks solid. A Power Star can also be found here after the player collects the eight Red Coins. This is the only location that Mario enters as Wing Mario; in other courses, he must collect a Wing Cap from a red block and either launch from a cannon or triple-jump to take off.

In Super Mario 64 DS, the red switch is changed from a ! Switch to a ? Switch, and its corresponding blocks are changed from ! Blocks to ? Blocks. In addition, only Mario is granted wings upon entering; if any characters other than Mario access the course, they still flip as they normally do during a course intro but plummet into the abyss, which promptly transports them back into the castle.

When Mario accesses the ? Switch course for the first time, it is mistakenly described as the "? Switches of Rainbow Tower" despite only one such switch existing in this version.

If the player falls below the stage, they will be returned to the castle lobby with no life lost.

Mission
There is only one Power Star to collect in this area. 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 pairs. Due to the fact that Mario slowly loses altitude while flying, he will have to reenter the level and try again if he drops below the point where the coins are. Additionally, each pair of coins going counterclockwise starting from the eastern side of the tower is lower than the last, meaning that it is most efficient to start with that pair while going in that direction. Once all the Red Coins are collected, the Power Star appears at the Star Marker on top of the tower.
