Super Mario 64

Face Distort:
When Mario appears, press A to get the hand. Grab a part of Mario's face with the A button and stretch it. To keep it there, press and hold the R button.
1,000 Coin Trick:
First, enter any Bowser level (the first being the easiest). Get to Bowser, instead of killing him, just keep dodging his flame attacks. Every time he breathes fire, he will drop coins. Keep collecting coins until you reach 1,000. After this point, an "M" will appear by your number of lives. Now, exit the level. Every time that you die, you will gain a life instead of losing one. However, if you gain any 1-Up, you will lose one life. Also, be wary that once you achieve 1,000 coins, you cannot save the game with this trick. So if you restart, you need to repeat the trick.
Kick Walk:
While sliding down a slope, jump up, kick in the air and pull back while kicking. Repeat to go up a slope.
Find Yoshi:
The final event you can get in Mario is obtaining Yoshi. The first requirement you have to achieve is to collect all 120 stars in the game. Once this has been achieved, proceed to the outside of the castle. The gate near the pond will be open and a cannon will be in there. Fire yourself onto the roof of the castle and there, wandering aimlessly, will be Yoshi. Talk to him to receive 100 lives and a new Triple Jump. Water Trick:
Any time you are really damaged, jump into the water, and float on the surface. Your life will then completely recharge. Mad Penguin:
Get the baby penguin to his mother. After she gives you the star, pick up the baby again. The mother will take on a mean facial expression and start running after you. She won't hurt you, just push you about and whine. However, if you have any distance out of the pond, she will stop and just stare at you. Baby Penguin Tricks:
By doing Mario's dive while near the penguin will make him dive as well. For a shortcut on taking the baby to the mother, jump off the ledge containing the starting point of the ice slide. The snow will break your fall on the ground, so don't worry about damage. Just pick up the baby again, and then proceed straight to the mother, who shouldn't be too far away from where you will land.
