Professor Egad isn't in the game.
Luigi is not in super Mario 64 on the Nintendo 64, that was a rumor. However, on the ds version you can play as him along with Wario and Yoshi.
You can't without cheating.
Because it was part of the plot? Why did you ask? It happens in Mario Galaxy though not Mario DS
when you get in the castle stand on the sun and keep your finger on x then hit the red box and you will get wings then go to cool cool mountain and click that red box and you will get the wings to fly over the mountain.i hope this helped you loads if it didn't terribly sorry.
you must talk to the snowmans body and beat him down the mountain then find a way to stop it... sorry i can't be of more service...
use me or Yoshi or Mario or wario
You need this key to get to the top of the castle. Do to the lobby and go upstairs, the gold door with keyhole, it takes you to the thrid floor with more painting!
64 is a cool number.
As Yoshi, hit a red block and get the flower to get the ability to spit fire and melt the ice for the red coin. if this is a bad answer I'm very very Sorry :(
The one in the mirror room on the floor with wet-dry world in it. The mirror shows a cool, cool mountain painting that isn't actually there. The mirror room is the one with the five pillars.
You dont!
it would be cool for different people. now super Mario 64 2 would be cool! (at least the one im thinking about where waluigi Mario luigi wario and Yoshi are playable with new features)
