Mario and Luigi Superstar Saga Final Boss Walkthrough

FINAL BOSS: BOWLETTA
HP: ???
Okay, so you go into the door, BUT save first!! Then Walk up to Bowletta, and after done talking, you'll enter a Battle. There are two parts to this battle, so try to save as many items as possible. Keep fighting, and try to stay alive. Once defeated, Bowletta will eat Mario and Luigi!! Then her ghost is inside her body's stomach. You'll only have 1 HP. So now, use a Mushroom to heal Mario and Luigi. Fight as hard as possible, use your strongest attacks, and eventually if you can stay live, you'll defeat her.
Congratulations!!!!!!! You've beat the game!!!!!
