Nintendo Direct announcement (04/17/2013)

 * Coins and Red Coins were slightly bigger and had a different design.
 * A level with yellow grass and red tulips nearly identical to Make Eggs, Throw Eggs from Super Mario World 2: Yoshi's Island was intended to be in the game.

E3 2013 trailer and demo

 * The logo for the game and title screen were simpler.
 * The Yoshis could swallow a Mega Guy by hitting it with their tongue once, like a normal enemy.
 * The 1-Up meter that appeared when the Yoshi obtained a Mega Eggdozer was different. The game also used a different font.
 * Gusty Glory was supposed to be World 1-2, but it was World 2-6 in the final game. Its background showed a forest instead of pine tree hills. It had a different design as well. The differing level number was likely for demo purposes.
 * World 1-3 was originally a castle-like cave where Count Fang was fought. The music used for this level was a remix of the main theme that, in the final version, was reworked and used for some specific rooms in Baby Bowser's Castle Break-In. In the final game, Count Fang is fought in World 2-8 and the cave became a section in Lantern Ghost Grotto. It was likely numbered 1-3 for demo purposes only.
