How to Beat the Third Bowser in Super Mario 64

The third and final Bowser battle in Super Mario 64 takes place in Bowser in the Sky, which is accessible once you have collected all 80 Power Stars. Here's how to beat Bowser and finish the game:

1. Before starting the battle, make sure you have collected the Wing Cap by obtaining the Wing Cap power-up from the cannon in the Castle Gardens and flying through the rings in the sky. The Wing Cap will allow you to fly and avoid Bowser's attacks more easily.

2. When you enter the arena, Bowser will start by throwing flame balls at you. Dodge them by flying around the arena and landing on the nearby platforms. Keep moving to avoid being hit.

3. Once Bowser has thrown enough flame balls, he will start running towards you. This is your chance to attack him. Fly towards him and aim for his tail. Grab it by pressing the "B" button, and then swing him around by rotating the joystick. When Bowser is dizzy, throw him by pressing "B" again. Make sure to aim him towards one of the bombs on the edge of the arena to deal damage.

4. After Bowser has been thrown into a bomb three times, he will retreat to the center of the arena and start using a new attack where he creates shockwaves by slamming his fists into the ground. Fly above the shockwaves to avoid being hit.

5. Bowser will then repeat the previous attacks, throwing flame balls and charging at you. Continue to dodge his attacks and grab his tail when he charges at you. Repeat the process of throwing him into bombs until he is defeated.

6. Once Bowser has been defeated, collect the final Power Star and enjoy the ending sequence!

Congratulations on beating Super Mario 64!
