The Tip Top Haven

 Basic Information 

Tip Top Haven is a level typically found in some copies of the 29/07/1995 build, taking place above the fourth or fifth floor. It is not confirmed if it was originally above the fourth floor or fifth, but due to the lack of photographic evidence of the 5th floor, it is assumed this takes place above the 4th Floor, potentially taking the place as the fifth floor.

 Evidence  Evidence towards the Tip Top Haven currently consists of 2 pieces of information.

1.) The level and it's name is present in the 29/07/1995 build, and it is called "tip_top_haven". this suggests this was intended as the last level above the clouds, visible on the beta screenshot patents Nintendo published in 1995, shown below. 2.) The only taken screenshot of "Tip Top Haven" was found, belonging to the Youtuber Greenio, who has recovered and published many tapes relating to Ultra Mario 64 and it's personalization antics.

3.) Big Chungus

Reportings

To date, only two reportings have been addressed, and even these have been hearsay. First, one player noticed when attempting to access this level from the fourth floor, the game will attempt to soft lock indefinitely, because of "Region Lock", potentially disguising and prohibiting the player from venturing further into the Tip Top Haven. Secondly, when a player accidentally jumped of the edge of the supposed balcony, the screen would fade to black, and a vibrant "Thank You" screen would be displayed, showing Mario looking out into the clouds, with Luigi and Peach standing together, which could reference that they have since died, and have left to go to heaven, although this is entirely speculation. After this screen, the Cartridge fries it's circuity after wiping it's rom, only leaving that image visible every time the cartridge it booted up again.
