Delicious Cake

Delicious Cake is a supposed area found in certain personalized copies of Super Mario 64. It is a large wooden platform with a big cake in the middle. On top of the cake is a star. When entering the level, dialogue that is believed to be Peach will appear:

"Oh Mario! Am I glad to see you! I baked this cake for us to eat! There's a problem... I'm stuck inside the walls. Mario, you have to save us from the Koopa King! I am channeling all my star energy just to talk to you Mario.. Please take the star atop the cake! Hopefully it will help you on your journey... Good luck Mario!"

It is believed this level was intended to be for a prologue. However, in some copies, collecting this star will unlock Peach as a playable character.

How To Access
Delicious Cake is accessed in a strange castle similar to the First Floor of Princess Peach's Castle, though lacking many details. Instead of the Second Floor key door, there is a room with a table and a cake on it. Touching the cake will send the player into Delicious Cake. The anomalous castle can be accessed with several techniques.

Second Serving / Extra Delicious Cake
Second Serving / Extra Delicious Cake are the names given to an anomaly where players can enter a new version of Delicious Cake after the first version with new stars. However, there is no proof of this anomaly, and it is unconfirmed this has happened.
