Part 1: Bowser's Keep and Mushroom Way
Mushroom Kingdom
Your next stop after treking through Mushroom Way is the Mushroom Kingdom, home of the Toads. The kingdom is more of a town, and you can poke around the houses and speak to the residents all you like. Ultimately, however, you need to head to the castle, which is northeast of the entrance to Mushroom Kingdom. If you're a completionist you should save before entering.
Once inside the castle you'll meet up with Toad, who will gab for a moment and then walk away. Sprint ahead of Toad (Y button, if you forgot) and wait until he stops in front of the door at the end of the hall. Jump onto his head and use it to hop onto the stonework above the door. There's an invisible chest up here that contains a Frog Coin. This brief window is the only time you can ever get this Frog Coin, so move quickly before Toad goes through the door and disappears. (Though don't worry too much if you miss it. Frog Coins are plentiful.)
Follow Toad to the throne room and you'll meet the Chancellor, who will hear Mario's story and beg him to hunt down Princess Toadstool. The Chancellor will provide you with a Map, which you can use via the menu to view the entirety of the world. That done, return to the main hallway of the castle and check the southeast doorway to find a small side chamber, where a Toad is guarding the castle vault. Inside you can pop open chests containing a healing mushroom, a Flower, and coins.
Head back outside. You'll catch sight of a burglary-in-progress, and a fluffy boy will trigger a rainstorm with his crying. Speak to him to learn that his name is Mallow, and a reptilian thief has stolen Mallow's Frog Coin. After demonstrating his jumping ability (B button) Mario agrees to help get the coin back. Mallow will hereafter join the party, providing Mario some backup in combat. Mallow isn't a great melee fighter, but his Special Moves - offensive and healing - more than make up for his poor combat skills.
Your next stop is Bandit's Way, an outdoor area similar to Mushroom Way. First, though, you should finish looking around the Mushroom Kingdom.
- Next to the spot where you met Mallow is a building with a star sign out front. This is the Inn, and you can fork out three coins to rest here for the night. This will restore the party's HP and FP. You'll also find a save point inside. Inns throughout Super Mario RPG will always have the telltale star out front, and you should make a point to pay them a visit and save whenever you find a new town.
- On the east side of Mushroom Kingdom is another building with a sign out front, this of a mushroom. These buildings are Item Shops, and will provide you with restorative items, new equipment, and accessories. Speak to the owner and he'll give you a free Pick Me Up, a handy item that will restore a knocked-out team member to life. You should at a minimum buy a Shirt and Pants from this guy before you leave, and equip them on Mario and Mallow. Some Mushrooms and Honey Syrup can't hurt either.
- On the right side of the Item Shop are stairs to the basement. A Toad down here will order you to stand in front of him and jump, revealing a hidden chest containing a Flower. This is a tutorial for invisible chests, of which there are many in Super Mario RPG. Wait for the Toad to amble over to the right-most corner of the room, near the bottom of the stairs, and you can use his head as a stepping-stool to reveal a second hidden chest, this one containing another Flower.
Head to the southeast end of Mushroom Kingdom once you're done looking around. There's a hop-happy Toad over here, and speaking to him will reveal the thief, Croco, who will skip town. Better follow him.

- Near the eastern exit is a Toad being chased by a Shyster. Save him to receive 10 Coins.
- In the main hall you'll see a Toad being chased by a Shyster. Defeat the Shyster and the Toad will tell you that the other Toads are hiding in the princess's bedroom, in the west wing of the castle. Fight your way in and you'll find a save point. The woman standing by the bed will fully restore your party's health. If you wipe out enough Shysters to get the Toad into the bedroom he'll give you a Flower Tab.

- Check the bedroom across from the vault. In a corner of the east side of the room you'll find the vault guard. He'll give you a Wake Up Pin. It prevents Sleep and Mute, and is a good accessory for Mallow since he can't do much without his Special Moves.

- Flame Wall, a multi-target Fire attack
