Big Bossdown

In the Big Bossdown, you can fight all the bosses you fought before. (Excluding secret bosses) There is a Pearl Sprite between every boss so you can restore your energy. If you beat every single boss including Mega Mashtooth, you win. If you finish under 9 minutes, you'll unlock world ten. (Note: If you finish at exactly 9 minutes, you will not unlock world ten. You have to finish at 8 minutes 59 seconds or less in order to unlock world 10.
