The Simpsons Bart's Nightmare

I can hear you saying: "Bart Simpson lost his homework? Suuure. What's his lame excuse this time?" Hey, I swear, I fell asleep! What a nightmare. Eight levels, each one scarier than the last, with villains like Homer Kong, Momthra, and Barney Gumble riding a pink elephant. I have to collect a page on each level, before I wake up and blow the whole assignment. You're my only hope, man.
