Mario & Luigi: Superstar Saga/Plaza and Koopa Cruiser

There are no enemies in the plaza area, but there are several items that can be obtained. The first one is a Mushroom in a block on a green ledge near the left edge of the plaza. With good timing, you can make the jump from the ledge to the left of it to the ledge with the block. On the right side of the plaza, there is another block, also containing a Mushroom.

The next three items require interaction with characters. On a light green ledge near the right edge of the plaza, there is a Mushroom out in the open. If you get it, a Toad will ask you if he can have it. If you tell him yes, he'll let you keep the Mushroom and he'll give you a Super Mushroom. In the top-left corner of the plaza, there is a Toad with a blue head who has lost his precious object. You can find it if you run to the southern edge of the platform you're standing on. Return it to him for a 1-Up Mushroom.

Once you've found all the items, go north. The first Save Album of the game is here. Head north again, but Toadsworth will stop you before you leave the area. He gives you a suitcase and 100 coins. Head north to the Koopa Cruiser. There, Bowser calls his baddies, and thinking that Luigi is one of them, pulls him aboard the ship.

Koopa Cruiser
Enemies: On the ship, the loudspeaker tells the Mario Bros. to go to the deck. Go to the right. Continue along the path in the next room until you reach a Bros. Block (a yellow block with an arrow on it). The Koopas slightly north of it explain how to get coins from it. Alternate pressing and  to collect coins. Exit the room to the southeast.
 * Goomba: 4 HP, 4 EXP

In the next room, there is a photographer with a camera. He'll take pictures of the Mario Bros, and you can change their position by pressing. Continue along the path and hit a ? block for a Mushroom. Go south and there will be another ? block and a Koopa. In the ? Block, there is another Mushroom. The Koopa will give you a 1-Up Mushroom if you helped him find Bowser when you were in the plaza. Go north again and then go to the room on the right.

Follow the path, pushing the barrel that is blocking your way. A Koopa will reprimand you, but then he'll offer to teach you how to fight. If you say yes, he'll break the barrel and you'll get to fight a Goomba. Continue on the path. There will be three more Goombas that you have to fight, and a Koopa teaches you that you can do damage if you jump on an enemy to start a battle.

There is another save album in the next room. Hit the ! Block and the crane will be activated. However, it will pick up Luigi instead of the cargo blocking your way. It takes him to the deck, where Mario joins him. A Koopa tells Bowser that the Koopa Cruiser will soon arrive at its destination, but Cackletta and Fawful show up.

Boss
Fawful
 * 32 HP
 * Three Attacks
 * "Fink-rat!" He shoots a fireball. If the text is red, he attacks Mario. If the text is green, he attacks Luigi.
 * "Have you readiness for this?!?" He shoots two fireballs. The brother he attacks first depends on the color of the word "this".
 * "Now is when I ram you!" He does a somersault forward at one of the Bros. This can be countered if you jump on him.

This battle is very straightforward. Partway through the battle, Bowser will tell you how to dodge the fireballs. Just jump to dodge his attacks. Once he takes 18 damage, he loses his headgear and uses his ram attack. If you get in trouble, use one of the many Mushrooms you have picked up, but it probably won't even come to that.

After the battle, Fawful shoots a barrage of fireballs at the Koopa Cruiser. It crashes down into Stardust Fields.
