Mario & Luigi: Superstar Saga walkthrough! This is a massive game (believe it or not) and I will sadly never finish it. I got as far as Joke's End (right before Joke's End, by the way) before I decided it wasn't worth finishing the guide and called it quits. If you get that far, you should be able to figure everything out on your own and shouldn't have too hard of a time with the final bosses. Cackletta's Soul will take you a few times, though!
