To defeat Bowser in World 2 of Super Mario Galaxy at Bowser's Lava Lair, you need to navigate through the lava-filled level while avoiding enemies and hazards. When you reach Bowser, use the environment to your advantage by dodging his fire attacks and jumping on the platforms. When he slams the ground, he will create shockwaves; wait for him to become stunned, then jump on his head three times to defeat him. Be sure to collect any nearby Star Bits and power-ups to aid in your battle!
