Koopa will come down in his nefarious Clown Pot. Don't touch the propellor on the
pot as it will hurt. He will swing backwards and forwards across the screen and
then stop to the right. He will then throw out two MechaKoopas. Jump on them to
knock them out and then throw them into the air so Koopa swings into them and
hurts himself. If you missed then he will stop and throw out more. After he has
been hit twice he will fly away and flames will fall from the sky. Stand in between
two of them and you will remain safe. Princess will throw you a Mushroom which
you should avoid if you still have full power. Koopas second attack will begin. He
will follow you around and then drop two huge boulders on you. Stand to the right
of the screen and when Koopa stops moving, run to the left and jump over the
boulder. Run to the right until he drops the second one and repeat. Now move out
and he will throw two MechaKoopas. Pick them up and run away from Koopa and
throw them up and he will follow you right into them. Hit him twice and he will go
away again. Flames and the Princess throwing a Mushroom will repeat and then
Koopa will return with the third and final attack. The Clown Pot is angry now and
will smash down on the ground. Run back and forth under the Clown Pot each
time it jumps up and he will stay in the middle. He will stop and throw two
MechaKoopas. Hit them, pick them up and throw them into the air so they drop
down and hit Bowser on the head. Hit him twice and he will eventually give up,
drop the Princess and fly away. Sit back and watch the ending sequence.
