David and Chef are on a hillside near a path to a tall pinpoint mountain.

Chef: There it is. The Mountain Ruins.

David: Why are we going there?

Chef: I heard there is some powerful creature living there. We might need some help there.

David: Sounds dangerous, but OK. Let's go.

Chef and David made their way to the mountain, where they came across some Shellpods and Boom Primids. Master Chef fire at the Shellpods and Boom Primids, taking them out. David and Chef proceeds forward, dodging some Jyks, and jumping over a series of spikes on the ground. When they reached the next area, they got ambushed by some Puppits and a Shellpod. David uses Jajanken Scissors on the Shellpod, while Chef fire at the Puppits. They took out the enemies and proceed to the next area. They broke through a series of blocks that leads to a tunnel with an elevator. They used the elevator and it takes them up to a cliff, where they got attacked by giant totem-like enemies called Gamygas.

David: What are those things?

Chef: I don't know, but we better take them out!

Chef takes out the Gamygas with his sword. David and Chef proceeds to the next area, where they encountered more Puppits and Borboras. David uses Jajanken Paper on the enemies, taking them out. He and Chef then came across a series of platforms in a canyon. They jumped over the platforms, which as soon as they landed, the platforms started sinking. They repeated the process, while also dodging the Jyks, until they reached the end of the canyon and entered a tunnel. The tunnel has a huge lake of lava and some more platforms.

David: Great! Now we have a lake of lava to cross over?

Chef: Look on the bright side. At least there are more platforms to jump over.

They jumped over a series of more platforms over the lava lake and reached the end, where they got attacked by the Fire Primids. There was also a series of fire pillars in the tunnel. David delivers punches and kicks on the Fire Primids, taking them out. Chef saw a button on the ceiling and jumps over to press it, deactivating the flame pillars. David and Chef proceeds through the tunnel until they got ambushed by some Armights. Master Chef takes out the Armights with his sword and David and Chef jumps down the pit and proceeds to the next room, where they got ambushed by Normal Primids and fire versions of Glunders called Glires.

David: Look out! An ambush!

Chef: At least those are weak enemies, so they should be easy to take out.

The Glires opened up their bodies to unleash fire, but David and Master Chef easily dodges their attacks. David grabs the Glires with his fishing rod and threw them at the Primids. They took out the enemies and proceed to the next room, where they encountered some Trackballs and Nagagogs. The Nagagogs body slams Buster Blader, taking him out. David hits the Trackballs to take out the Nagagogs. He and Chef proceeds to the next room with a big platform and two floating platforms, where they got ambushed by more Glires, Fire Primids, and Scope Primids.

David: Oh come on! How many more enemies are there?

Chef fires red energy beams from it's two heads at the Glires, Fire Primids, and Scope Primids, taking them all out. David and Chef proceeds to a huge room with a big platform with three floating platforms. They went on the platform and it moves up, where they got ambushed by more Glires and Armights. Chef uses Swords of Revealing Light to trap all the enemies with his light swords, allowing David to take them out with his Jajanken Scissors. They proceed to the next room with an elevator. The elevator takes them up to the front of a temple inside the mountain.

David: Hey Chef. Is this the right way?

Chef: This is the entrance to the Mountain Ruins. This is definitely the right way.

?: Sorry, kids. But you made it this far!

They looked up to see someone jump down at them. The two boys leapt out of the way. Bengt is right in front of them.

Bengt: Hahaha! Don't think I'd let you get away so easily.

David looks up and gasps.

David: You! You're the one who took away Anne-Marie!

Bengt: Oh, it's you again. What's the matter? Gonna run away again?

David: No! This time, I'll make you pay for what you've done to Anne-Marie!

He grasps his fist and got in his stances.

Chef: That goes for Charlie too!

Chef got in his stances too.

Bengt: HA! You think a couple of kids like you could defeat me? I'll crush you both!

The battle begins with David using Fortify to increase his defense and punching Bengt, but his fist went through Bengt's body, which was made of sand. Bengt uses Desert Spada to turn his right arm into a sand blade, stab David, and strike the ground with his blade, creating a fissure of sand. Chimera slashes at Bengt with it's claws, but it's attack went through Bengt's body. Bengt then stabs Chimera with his Poison Hook on his left arm, damaging it. He then uses Sable to create a sand tornado, destroying Chimera.

David: It's no good! Not only is he powerful, none of our attacks are working against him!

Bengt: Fools! It's because I have the powers of the Sand-Sand Logia Fruit. It makes me invincible to any physical attacks.

Chef: If Bengt is invincible to physical attacks, then there is only one other choice to stop him!

When Bengt uses Desert La Spada to fire sand blades from his left arm, Chef traps Bengt in a magic circle.

Bengt: WHAT? What is this?

Chef: It weakens your powers and you cannot attack!

David: That was incredible, Chef! Now let's finish him!

Chef fires a sword cutter from his sword at Bengt, doing alot of damage to him.

Chef: That was for Natsu!

Then David uses Jajanken Rock to deliver a powerful punch on Bengt, doing alot more damage to him.

David: And that was for Anne-Marie!

The last attack sent Bengt flying to the air.

Bengt: This can't be! How could I lose to some brats? AAAAAHHHHH!

He disappears into the sky and came down in his trophy form.

David & Chef: We did it!

They high-fived. David then remembers about Anne-Marie. He looks around for him, but he wasn't around.

David: I wonder where Anne-Marie is.

He looks down in sadness. Chef puts his hand on his shoulder.

Chef: Don't worry, David. We'll find him. But right now, we have to explore the Mountain Ruins.

David nods and they turned to the ruins and entered it. Meanwhile, back at Prudence Petipas's Castle, Prudence Petipas was busy looking at the trophies he had taken from Bengt. He had just finished dusting off the Anne-Marie trophy.

Prudence Petipas: Ahh, much better. Hmm...One thing missing.

He pulls out two Prudence Petipas badges from his "sleeves" and places them on Tommy's nose and Anne-Marie's shirt. As he was about to put one on the Annika trophy, he realizes he was all out. The last one was on him. He sighs and takes it off and places it on Annika.

Prudence Petipas: There...better.

Then all of a sudden, a rumble was heard throughout the castle. Prudence Petipas looks around to see who it was. Then he saw the roof was falling on him. One part of the ceiling hits him on the head.

Prudence Petipas: Ahh, what pretty little birds.

He fell to the ground. As the rest of the roof fell down, Thunder-Karlsson and his troops leaps down and looks around.

Thunder-Karlsson: Hmm...Now where is that Annika trophy?

As he and his troops looked under the rubble, he found what he was looking for.

Thunder-Karlsson: Ahh, there you are!

He picks up the Annika trophy and went through a hole in the wall. Under the rubble, the Anne-Marie and Tommy trophies were laid on the ground and Prudence Petipas was turned into a trophy as well.
