Yoshi mode
Successfully complete the entire game of Super Mario Brothers 2 to unlock Yoshi mode You do not need all the red coins. In Yoshi mode, you must find two Yoshi eggs hidden behind the potion doors. There are two eggs for each stage.
Bald Birdo
Get to a part in the game where you fight Birdo. Jump on her head and press [B], as if you were picking a vegetable. You will pick up her Bow. You can either throw it at her, which causes it to appear back on her head, or throw it off the edge or something so she is bald.
Defeating Claw Grip
Get on the edge to the right of the hole. Claw Grip will throw a stone that should bounce to your small standing space. Quickly time it correctly so you can pick it up and throw it at him. Do this five times.
Defeating Mouser
You will need to use a character that can throw well. Get Mouser to destroy the wall with his bombs. Once the wall is passable, carefully go to the ledge. Wait for him to throw a bomb. It should automatically be picked up. Then, throw it lightly onto Mouser's ledge. Timing is required to have it explode in Mouser's face. Do this five times.
Defeating Tryclyde
Play as Peach. Quickly pick up a mushroom block before they hit you with fireballs. Float on the open ledge opposite from the three headed snake. Float towards the thing and drop the mushroom block on it three times. It will yell "Impossible!!!", signaling you that you have defeated it.
Defeating the flying portal and Wart
When at the portal to reach Wart, pick up the crystal and advance to the portal. Carefully use the mushroom blocks and hit the portal with them. To beat Wart, get a vegetable, go behind him, and throw it while he is firing at you.
Use Peach for this battle. Get a fruit and avoid the bubbles that appear from his mouth. While he is harmless and motionless, hover over his head behind him. He cannot hurt you from this point. When he opens his mouth to fire bubbles, throw the fruit at him from the back of him. While he is stunned, fly back over to the front of him. Collect another fruit, avoid the bubbles, and repeat the process five more times to defeat him, most likely without being scratched.
Free hearts
Find a giant enemy and throw them. Do not through them off a ledge or into an enemy. A heart will pop out of them. You can do this as many times as needed if you do not kill them.
Pick up POW block
In Mario Bros. Classic, go on top of a POW block press [B].
Character recommendations
Mario: The main character has basic, balanced stats, and is a good choice for beginners.
Luigi: He is very fast and has lots of power, but on the downside is very clumsy.
Peach: She can float in the air while holding [A] button for about 1.5 seconds. However, she is the weakest in terms of power and speed.

Keep doing this to get as many lives as needed.
When you pick up a turtle shell and launch it, any enemy on the ground it hits will give you a heart. Hit multiple enemies for points.
