In a lush, fertile land, the Wetnosaur stomps through the land, looking for vegatation to eat. As the creature eats some leaves off of a tree, the Chomposaur comes by and tries to eat the Wetnosaur, but the Wetnosaur strikes it with its tail. As the Wetnosaur and the Chomposaur fight, our heroes watch from a distance.
"Dinosaurs?" said Ness. "Wow, I thought they went extinct?"
"Me too," said Jeff.
"Let's get out of here before we get eaten," said Paula.
Our heroes head north and come across a barricaded village. A voice is heard from the other side of the gate.
"You guys smell really good!"
"Who are you?" Ness asked.
"Who am I? I'm the Tenda leader here! Is that Tendakraut you have?"
"Yes."
"Come in!"
The gate opens and the Tenda takes the Tendakraut.
"Thanks for taking it off our hands. It stunk to high heaven!"
"By any chance, are you kids what the Rock speaks of?"
"What?"
"Go over to the rock and speak to it."
Ness goes over to the rock. It begans to speak to him telepathically.
"You finally came, Ness. Finally, you talk to me. Listen Ness. I'm going to tell you something very important. You may want to take notes. Ready?"
"Yes."
"... You're the chosen one. Your destiny is not only yours... It's the destiny of the whole universe. There will be a time in which all of you in the universe will overlap each other. It's not necessary to understand now. Do you remember Giant Step in Onett? That is one of your Sanctuaries. It is a spot which gives you power and allows you to realize all your skills. There was a monster that protected it. The monster was influenced by a power of the place. You must have beaten those monsters. You must reach all of the eight power spots in the world... When the Sound Stone records the melodies of all eight power spots, you can finally see Your World. I'll tell you all of the power spots. Giant Step in Onett, Lilliput Steps in Peaceful Rest Valley near Twoson, Milky Well in Saturn Valley, Rainy Circle in Winters, Magnet Hill at the edge of Fourside, Pink Cloud in Poo's homeland, and Lumine Hall. A new place is now going to be opened up to you. Fire Spring, located southwest of here. Listen to the melodies of all eight power spots. If you do not fail, you may upset Giygas' plans... Understand, Ness? The time will come. The time when the destiny of you and the whole universe will overlap... It is fast approaching."
In the southwest area of the Lost Underworld, our heroes make it there, having barely out-runned the dinosaurs.
"Man, that was close," said Ness.
"Hey look, a hot spring!" Poo pointed out.
Our heroes then come across what's next to them: a geyser hole.
"Poo, this isn't a hot spring," said Ness.
"Sure it is, all you have to do is stand near the hole."
Everybody stands near the hole.
"Wait for it..."
Just then, the earth quakes.
"Ah! Earthquake!" Paula screams.
"No, better; hot spring water!" said Poo.
"What?"
Poo was right. Everyone gets jettisoned a hundred feet into the air by a geyser of soothing hot water. The geyser gradually goes down until everyone is on the ground again.
"I feel refreshed!" said Ness.
Just then, something floats down and lands in Poo's arms.
"The Cloak of Kings! My armor is now complete!" said Poo as he puts on the cloak.
"Wait a minute, Poo, if I'm the chosen one, then how come you got armor?"
"Um... I'm your soldier?"
"Okay then, that settles it. Poo's my soldier, Paula's my second-in-command, and Jeff's my technician! Now, let's go to Fire Spring!"
"Where is it?" Jeff asks.
Ness uses his powers to locate the final Sanctuary.
"In... the volcanoes? Guarded by a dog made of magma? This isn't going to be easy... but we CAN'T back down!"
So, our heroes go inside the nearest volcano. They carefully navigate through it, avoiding getting burnt or inhaling smog. After what seems like hours of navigating (more like a half hour), they make it to the top. Ness then senses something at the end.
"Wow! That dog seems to be even stronger than I thought! It's as if there were 2 of them! Or maybe I'm just nervous about our future..."
"Ness, relax," said Paula. "We'll be there for you."
"Okay."
Our heroes then reach the end, where the fiery dog resides.
"You finally got here. This is the eighth and final Your Sancuary location. But it's mine now. Take it from me, if you dare..."
Ness began to quake in his shoes.
"P... PK... PK FLASH!"
Ness's attack connects with Carbon Dog, who is weakened by it. The dog tries to retaliate with a PK Fire blast, but everyone avoids it.
"PK STARSTORM!"
Poo's attack strikes at Carbon Dog, weakening it some more.
"PK FREEZE!"
Paula's attack encases Carbon Dog in ice.
"See, Ness? It wasn't so hard," said Paula.
"I guess you're right," said Ness. "I was really scared for a second. Now come on, the final Sanctuary is right... uh-oh."
"What?" said Jeff.
"I sense that the dog isn't defeated yet."
Ness was right! Carbon Dog gave off a rainbow of colors and transformed into Diamond Dog!
"Oh no, what have I done?" said Paula.
"It isn't you, Paula, it's me," said Ness. "The truth is, I'm afraid of what will happen to us."
"Ness, snap out of it! We need to defeat Diamond Dog!"
"Oh! Right!"
Diamond Dog then unleashes a glorious light, which diamondizes Jeff and Poo!
"Jeff! Poo! NO! PK ROCKIN!"
Ness uses PK Rockin on Diamond Dog, who, at the same time, starts to diamondize Ness. In the end, Ness triumphs with everything from the shoulders down completely diamondized.
"Pant... pant... Paula, are you there? Everything is getting dark..."
"Ness, eat these Lifenoodles we found," said Paula. "They're said to save one's life."
Paula feeds Ness the Lifenoodles, freeing him from the diamondization.
"Thank you, Paula... Urgh... so weak..."
"Ness, hang in there. You need to carry Poo while I carry Jeff."
Our heroes make it to Fire Spring. After bringing Jeff and Poo there, Ness collapses to the ground.
"Ness!" Paula cried.
"I'll be fine. I'm just... tired..."
Just then, the final melody plays, bringing Jeff and Poo back to normal.
"Ness, you did it! We've won!" said Jeff.
"Finally, we have fulfilled our destiny," said Poo.
"Um, guys?" said Paula. "Ness doesn't seem too well. He's lying on the ground."
As Ness weakly lays on the ground, his Sound Stone then plays the entire song. He then smiles and finds himself in another place. He sees what looks like his house, and enters it. Inside, there was Chibi as a puppy, barking. Ness heads upstairs and to his room, where he finds his parents with his infant self.
"Ness... Hmmm... I think Ness is the right name for him," said his father.
"Ness... he smiled just from hearing his own name," said his mother. "Do you think he likes the name?"
"Try putting that red cap on him."
The infant Ness has a red cap placed on his head.
"Hey, that's... me!" said Ness.
"Ha ha ha! It's too big, but it looks good on him..." said Dad.
"I hope Chibi won't be jealous of the baby," said Mom.
"Let's celebrate with some steak. The baby will grow up to be a hard worker just like you."
"I don't think he needs to be rich or famous, but I want him to be a thoughtful, strong boy."
Just then, the baby bottle is moved by the infant Ness' PSI.
"That's odd... the baby bottle that he pointed at seemed to move a little bit..."
Ness watches his infant self move the baby bottle back to where it was. And then, a bright white light flashes...
