Chrono Trigger/Tata and the Frog

Tata and the Frog (600 A.D. second time)

Denadaro Mountains
This chapter technically begins when you run into Tata at the Denadaro mountains, so we'll just take it from there. Make sure you have Lucca along in your party so you can burn the hammers of the Ogans you meet. Head up the ladder in the first area, and head through a south exit to pick up a chest you saw earlier. This next area is fairly linear, just fight all the monsters and exit to the north-east.

The next area is pretty linear as well, just mosy around until you pick up all the chests, and I'd recommend fighting all the monsters as well just to level up. Watch out for the free lancer throwing rocks in the area after that, they actually do lower your health. Walk through another short area, and heal up because the next area you fight in will be a cliff where you have to fight through four consecutive groups of monsters. Have Lucca burn the Goblins with hammers as always, and heal with Aura Whirl or whatever you have available.

The next area will look like a giant waterfall. After one brief fight, you'll discover you can jump down the river down the center or the bottom left. Head down the bottom left path to jump to some ledges with two awesome items, a SilverStud and a Silver Earring. The Stud cuts MP use by 50%, and the Earring raises your HP by 25%. You'll walk around to where the cliff was and return to the waterfall area. Talk to the free lancer if you want, then you'll fight him and exit to the left. The next area just has a Kilwala that will give you a Magic Tab if you talk to him four times.

After that you'll come to a save point, although you have a few more fights before you can reach the boss. Go down the ladder and check the bottom left area for an easily missed Speed Tab. Move on, jump down a ladder and climb up another one to find a cave where the boss is.

When you finally beat the boss, you'll get the blade of the Masamune and ride the wind to the base of the mountain. Go to Tata's house to the south to learn the truth about him and the medal, and make sure to rest since the game isn't nice enough to restore your health after boss battles. Head into the cursed woods, and give the medal to Frog. He'll give you the hilt of the Masamune, which you'll learn was made by Melchior, a man living in 1000 A.D. at Medina Village. Head out through the woods, remembering to attack the snakes to make them eat the frogs.

Go back to the time gate in truce canyon, and take the time gate to Medina village to speak with Melchior. He'll explain that his story involving the sword is a very complicated one, but he could reforge it if you could bring him some dreamstone. Unfortunately dreamstone hasn't existed for millions of years now. Sounds like the time is right to take a trip into the past, doesn't it? After talking to him, you'll be in the next chapter for your save file, so let's move on.

Challenging Lavos
While the save file still reads, Tata and the Frog, head to the Millennial Fair if you want to fight Lavos at this point and get The Unknown Past Ending. This ending shows a few scenes from 65M B.C., since you haven't had the chance to go there yet if you beat the game at this point.
