Trailer 2

 - The camera in Cavern Catastrophe is different.

 - Uka's eyes are misplaced.

 - The crate layout is different, with random platforms around the area where the 3 switches are.

 - Slip Slide Icecapades' long rail contains the green gem instead of the crystal.

 - The purple gem is placed above a rock in the second part of the N.Sanity Island hub instead of at the puzzle in the back of the picture.

(Although, the player could have entered the cutscene through special means)
