Kirby, Kine, and ChuChu are back in the throne room with King Porposeidon and Queen Shira. Behind the king and queen are seven dolphins holding a single Power Pearl each in their flippers.
Porposeidon: Well done, you had delivered all seven Power Pearls to us. For that, we are eternally grateful.
Kine: No biggie! Now that you and your city are completely safe from harm, isn't it time to return the favor?
Shira: Of course. Could you give us a moment?
The servants immediately leave the room with the Pearls.
ChuChu: Wait, aren't you going to turn Kirby back to normal?
Porposeidon: Not until we tell you the end of the story first.
Kine: Well it's not like we're in a hurry or anything.
Porposeidon: The ones who took the six Pearls were smart enough not to try to retrieve the last one from us. You see, the thieves who did it were our own kind. Once they have realized the truth of what our machine can do, they stole and hid the Pearls so that it can never be activated. The Pearls were taken to places that were impossible for us to get to. For too long we waited for someone naive enough to bring them all back to us, until now!
Multiple dolphin guards rush in and surround the trio, pointing their weapons at them.
Kine: Uh, what's going on here?
The king and queen start laughing in their own language.
Shira: We're just reveling at the fact that we used you all to get what we want!
ChuChu: I don't understand.
Porposeidon: Of course you don't, that's why it was so easy! Did you really think we, an advanced civilization, get ourselves attacked by mere pirates? We're the ones who orchestrated all this. We created the Nauticrooks and programmed them to attack the Dolphinion in order to draw Dream Land's greatest hero to us! That's right, we all know about Kirby before you even came here.
Shira: Our scouts have been observing him for weeks. He was the perfect pawn, and we made you believe our sob story to lure him here.
ChuChu: But if you built those pirates, then that means...
Shira: We had two pearls all along! Our machines would've taken care of Kirby, but we should have known better.
Porposeidon: Now that all seven of them are together again, we can activate our ultimate weapon: Tsunamageddon!
Kine: I don't believe this, I thought you guys were cool!
ChuChu: Why are you doing this?
Porposeidon: Isn't it obvious? Planet Popstar has more land on it than water. We are sick and tired of swimming in the same oceans like its one big aquarium. But with the power of Tsunamageddon, we can change all that!
Shira: Now that you know everything, I'm afraid we can't let you interfere.
Suddenly, a giant cage drops down and traps the three inside. Kirby tries using his powers to get out, but to no avail.
Porposeidon: Good thing we came prepared. Guards, please escort our guests to their room. Keep them there until we accomplished our goal.
The guards carry the cage holding the trio out of the throne room as the scene fades to black. The next scene opens to the three trapped in a dungeon-like cell.
Kine: Well this is just great! For once, I would like to meet people who are not evil dictators wanting to rule the world!
ChuChu: I'm sure Kirby will get us out of here, he always does.
Kine: I doubt it. The only thing we escape is if someone from the outside came and busted us out.
Just then, Acro bursts in through the wall behind them.
ChuChu: It's Acro, he came to rescue us! But how did he...?
Kine: My best guess is that he knew about the Dolphinion's master plan all this time and was trying to stop us from collecting the Power Pearls. We're very sorry for Kirby beating you up and all that. You would have saved us a lot of trouble if you learn to speak English.
Acro: Acro can speak... but not... very good... at it.
Kine: Oh.
ChuChu: Now that we are free, can you lead us to where they are now Acro?
Acro nods.
ChuChu: Excellent! Now let's save the day again!
The three follow Acro through hole in the wall, then the scene fades to black. The next scene shows a gigantic mechanical shark lying dormant in the ocean floor. The trio and Acro slowly approach it.
Kine: So this is their secret weapon, call me impressed.
ChuChu: Looks like it hasn't been turned on yet. We beat them to it!
Just then, the shark begins to power up and rise to the surface.
ChuChu: I stand correct it.
Kine: We need to get inside that thing and fast!
The trio quickly swim to a nearby hatch and manage to get in. Acro watches as the shark fires its boosters on its underbelly and flies right out of the ocean and into the sky. The next scene shows the three inside a room full of pipes.
ChuChu: That was close!
Kine: Since the pearls are what keeping this scrap heap afloat, we need to find where they're keeping them so we can shut it down!
The three soon find themselves in a big room where they see a large generator with the pearls in its slots.
ChuChu: We found them!
Kine: Kirby, would you do the honors?
Kirby slowly swims towards the pearls. Before he can touch them, Porposeidon and Shira barge in and stop Kirby from doing so.
Porposeidon: Don't even try it, pal! We didn't come this far just to let you ruin everything!
ChuChu: You know Kirby will stop you, just like he stopped every other evil-doer!
Shira: You would side with this air breather instead of us, or even your own brethren? How pathetic!
Kine: You're pathetic! Kirby isn't just some air breather, he's a friend. Most of our friends are also from the surface, and they all know the difference between right and wrong. Sure there's more land, but we wouldn't have it any other way.
Porposeidon: Well that's too bad. After we deal with Kirby, you're next!
Kine: I like to see you try!
Kirby begins to fight the king and queen. Kirby defeats them, and the generator becomes heavily damaged from the battle.
Porposeidon: Your friend proved to be quite formidable, I'll give you that. But you're still going to lose. All we had to do is stall you long enough so we gain enough altitude.
Shira: Once the Tsunamageddon drops down to the ocean, it'll make waves big enough to flood every inch of your world. The Dolphinion shall rule it all once more!
Kine: You'll be sorry once Kirby gets a taste of all seven Power Pearls combined!
Porposeidon: I'm afraid not. Consider yourselves, drained away!
A big hole opens up in the floor, sucking the three heroes down. Just then, the seven Pearls start coming out from their damaged slots, sucking them down the hole as well.
Porposeidon: Ah well, at least it runs on reserve power.
The trio fall out of the hole from the underbelly, followed by the pearls. Kirby holds his breath long enough to move to the pearls. The Power Pearls start encircling around Kirby and a big pink light flashes before them. When they open their eyes, they are in a humongous water-based construct of Kirby. They see the Tsunamageddon falling down towards the water.
ChuChu: This is it! Either we save Dream Land or there won't be a Dream Land anymore!
Kine: Then let's do this!
The final showdown begins. Kirby fights it on and wins. Afterwards, the machine begins to break apart. The Kirby construct absorbs the machine into itself, letting Kirby go inside and rescue the king and queen. Then the four safely land in the water near the beach from the opening. They watch as the Tsunamageddon explodes, taking out the construct with it, making it rain for a few seconds.
Porposeidon: After all the horrible things we did, why would a simple-minded surface dweller like you save us?
Kine: Because he's a hero! That's what heroes do.
Shira: All we ever wanted is to have more ocean so that our lives would become much better than it already is.
ChuChu: And it can. Instead of spending your whole lives yearning or coming up with evil schemes, you should just be grateful for all the things you have now.
Porposeidon: You're right. It was wrong, and we apologize.
Shira: Our people had the right idea not to let such an awful thing be unleashed on the lands above. Will you forgive us?
Kine: Of course we do, we're cool now!
Porposeidon: Happy to hear that. Henceforth, the Dolphinion shall be better than our ancestors. Farewell, may our paths cross again.
King Porposeidon and Queen Shira return to their kingdom.
ChuChu: Now that's all over, what happens now?
The Power Pearls gather around Kirby, turning him back to normal self. As the Pearls vanish into thin air, Kirby swims back to shore.
Kine: You know, I'm going to miss all of your talents under the sea. If you need us, we'll be nearby.
ChuChu: Goodbye Kirby! We'll see you on your next adventure!
They wave goodbye to each other. As they go their separate ways, Acro takes one last look at the heroes and then swims out to sea.
The End.
