Made it so you needed 1 star to get into Bomb-omb battlefield? He would've won easily. Just 1 star you dingus.
The first toad still had one I believe.
Plus, Bowser screwed up and didn't realize how many stars were actually in the castle. He expresses utter surprise if you beat him with 120 stars, he had no idea there were that many because he only found 70.
