King Boo was flying to his house, but Mario was guarding it.
King Boo challenged Mario and Bowser to a race at Grumble Volcano.
King Boo shot right over a hole. Mario was impressed! He flipped over the hole - but Bowser was still in front. They crashed into Bowser and Bowser accidentally fell into Lava - but he survived.
The End.
Next : The Battle of Bowser, in a school near you.
