The SponbgeBob SquarePants Movie
GameCube - 1080p

Going into the depths of this game!
The hidden Level starts at 1:00
Exploring the screenshots floating in the air 3:55
Exploring inside of the Krusty Krab 5:30

-There are all screenshots from the Cutscene floating in the air.
-The Krusty Krab can''t be entered by I zoomed into it to show it's inside which is all there.
-The Level doesn't play any music

After finding that there is a Level called B402 in the SB04.ini file I decided I had to enter it and here is the video of it!


Guess what, the 100% Cutscene is in-game rendered.
But where does it take place?
Exactly, in a small Level which is hidden in the game's files and was specifically made just for that Cutscene.
How did I enter it?
Well, you will actually enter it every time the Credits start playing for an unknown reason, but you can't play it because the Credits overlap it.
So... I dummied the file which tells the game to play the credits, et voilà you will enter the Level after beating Neptune. :)

The Level has all the surrondings the cutscenes show like
-the trash at the back of the Krusty Krab,
-the advertisments for Krabby Patties lying on the ground
-the dirty funnel at the top of the Krusty Krab
Etc.
Inside the Krusty Krab is the deck chair seen in the cutscene,Mr. Krabs' desk, the toilet and more

The Level resembles the 3rd part of Battle for Bikini Bottom's Hub World.
The cinema, the Chum Bucket and the Flying Dutchman's Graveyard are missing but parts of the Kelp Forest are still there and somehow parts of the Sand Mountain.
