The Mega Goomba grows after touching a mushroom that uses a tinted version Super Mushroom graphic from Super Mario 64 DS. Mario can move during the Mega Goomba growing cutscene. He can perform backflips and sideflips like in Super Mario 64 DS. He can perform triple jumps with much less speed and movement distance than the final game. Mario's physics are looser and slightly buggy, he can also do moves that he couldn't do in the final game, such as:. Bowser uses a standing pose, doesn't move, and is in an overworld area. Mega Goombas are smaller and animate differently. Mario uses different animations, reminiscent of Super Mario 64 DS. None of these tilesets and backgrounds appear in the final game.
Goombas and Koopas use 3D models, the models still exist in the final game (though the Goomba model is used for the Mega Goomba). The Question Blocks, Brick Blocks, and Pipes use different cartoonish graphics. No HUD is present (on the top screen at least). Hitting a ? block does nothing but plays the ! box breaking sound from Super Mario 64. Enemies defeated by Mega Mario all make the sound Goombas make when they are stomped on in Super Mario 64. Enemies defeated by fireballs all make the sound Spindrifts make in Super Mario 64 when stomped. Coins are lower pitch, use Bb-Eb like Super Mario 64 and Super Mario Sunshine instead of B-E. Different sound effects play when hitting blocks, shooting fireballs, when fireballs burst, enemies are attacked and when bricks are broken.
Mario uses different voice clips taken from Super Mario Sunshine and Super Mario 64 DS. Mario speaks when performing normal jumps like 3D games.
