Successfully complete the game to unlock Time Trial mode.

Time Trial mode features five extra levels (one for each world) and the ability to play as a black Yoshi.
Rotating arrow
You can swallow the rotating arrow in any stage it appears in.
In-game reset
While playing the game, press L + R + Start + Select.
Feet remains still when flutter jumping
Make Yoshi do the flutter jump. Just when he is doing the flutter jump, press X (or R if you switched the controls) to make Yoshi aim his eggs. Notice that his feet stay still when they are actually meant to kick around while he is flutter jumping.
Enemy is Yoshi’s mouth
Get DK if you do not already have him. Swallow an enemy, then climb on a vine and reach out. You should still have the enemy in Yoshi’s mouth; however, it is not. When you drop down, notice the enemy is back in Yoshi’s mouth.
