It was an intense day in the Mushroom Kingdom; Bowser had kidnapped Peach again. Mario, Luigi, Toad, Yoshi, Wario, and Donkey Kong had all given chase to him.

"Fools, you won't be able to stop me this time!" Bowser snarled from his Koopa Clown Car.

Mario came back at him with a determined "You always lose; what makes you think this time will be any different?"

Bowser held up a balloon filled with black fluid; "THIS! Courtesy of Vibe Island!" He launched it at the heroes. Before it could hit anyone, without a second thought, Yoshi grabbed it with his tongue and ate it. He flinched and spat out the plastic, but he was still able to catch up with the others before inexplicably tripping. Bowser grabbed a pink one and hurled it at Wario, but it hit Donkey Kong instead. The force of the impact splattered the paint all over him and he fell back. The same went for Toad, but this time, the balloon thrown at him contained green-colored liquid.

Mario stopped at that moment; the heels of his boots screeched against the path. He attempted to calm a crying Toad down when suddenly, he twitched then just started feeling better despite still being covered in green paint. Donkey Kong experienced the same, except he asked if they were ok.

"Yeah, we're fine." Mario said with a sigh of relief.

"Phew! That was so close you guys. I thought we were in serious danger; I hope Luigi and Wario are okay."

"Um, DK, since when are you become this concerned about our well-being?"

"I don't know, but now I wanna hug you for some reason!" He then did the best he could to wrap all three of his friends in his arms, pleasing them while creeping them out.

After DK let go, Mario thought about what had happened some more. "Bowser said he got them from Vibe Island-that must be where he's taking Peach! Toad, how are you feeling?"

Toad was about to speak but was interrupted by an obnoxiously rude voice; "Oh sure, like you couldn't make that connection. I'll have no problem defeating you in my quest to take over the world! Bwahhahahahaha!" The voice sounded like it came from Yoshi, but something so mean couldn't have possibly come from him. He tried to speak, but his now black tongue was not moving. Then, suddenly, it rose up on its own, opened a pair of eyes and insulted Donkey Kong's pink fur. Everyone was grossed out by it. Yoshi slammed his mouth shut with his hands, but the tongue just kept wanting to control him.

The group decided to head forward quickly; who among them knew what kinds of trouble Luigi and Wario were going to get themselves into. They continued following Peach's screams until she was too far away, then another road hazard: the ocean. Fortunately for them, Toad pointed out a small port that the trees had blocked prior.

They went up to the manager. "Hey guys, what can I do for you and what happened to you guys—You need something for Princess Peach?" he guessed.

"We'll explain that later; this is an emergency! Say, have you seen Luigi and Wario anywhere?" Mario gasped.

"Oh, funny thing, they just left on the S.S. Briskley to chase after Bowser; it's the fastest one we've got, and Wario was in such a rush, he didn't even pay."

Mario spoke with a frenzied tone in his voice while giving the captain a bag of Coins: "Heroes' discounts to a' Vibe Island please!"

"Okay, there's one over there you can use." Mario, Toad, Yoshi, and Donkey Kong all got on board and sailed towards the island.

Meanwhile, out in the middle of the ocean, the S.S. Briskley caught up to Bowser. Luigi climbed up to the top of the boat and after making sure he had solid enough footing, he jumped towards Bowser's Clown Car, sure he was going to reach, but Bowser moved it to the side just as Luigi almost had the edge in his grasp. The captain slammed the brake, so Wario had more time to align himself to save Luigi from the fall, but they couldn't catch up to Bowser anymore.

"You dummy! I totally could've caught him without that!" Wario boasted, "Now we're even MORE behind!"

"I'm just doing my job!" the Toad Captain Knot T. cried shivering, "You still haven't even paid me!"

"Fine; it's not like we have anything better to do." Wario gave Knot. T two handfuls of Coins from his pockets.

When they finally reached Vibe Island, they were treated to a beautiful, open valley. Bowser was hovering over a large mountain just to see what they would do. Wario stuck his tongue out at Bowser and declared to his partner, "C'mon, Luigi! We're a' going mountain climbing!" Wario tried to find a place where he could gain his footing, but he never could.

Bowser laughed at and taunted them, then disappeared into the valleys. Wario did not take that well. "I'm still a' gonna get you Bowser," he grunted as he still tried to advance upwards.

Shortly after that, Wario and Luigi heard a horn blare and could see another ship: it was the others! "Luigi shouted with excitement, "Hey, I think that's..."

Wario interrupted, "Bah, I may not be the best hiker, but I believe I can still reach Bowser myself! You comin' with me or not?"

"Well..." Luigi spoke nervously while twiddling his thumbs.

"Shotgun!" Wario ran off into the plains before he even had time to think. Luigi stood there. "What just…Come back!" He then yelled out to the ship. When no reply came, he sat down on a rock, waiting for one to come. A short time later, he was startled by loud, merry singing right next to him to the point of falling back.

When he got back up, he looked at the rock to see where the sound came from. There were two floating, living, breathing, heart-shaped beings; one sad and blue, one smiling and yellow. The yellow heart squealed in excitement. Luigi rubbed his eyes and asked them who they were in astonishment.

"We are Vibes, living embodiments of emotion. I'm Gloom and that's Joy," The blue heart said. Luigi courteously got down his knees to get at their level.

Joy spoke in her usual excited manner, "We sensed your feelings and ventured out of a hidden cave.

"What are the others like and where are they?"

Gloom sighed, "That big, bad, giant Koopa returned and has our friend Peach and lots of the other Vibes hostage. He performed cruel experiments on them, creating weapons against anyone who opposes him that, regardless of emotion drives them mad and likely to their demise. Will you help us mystery man?"

"Of course."

Mario's voice echoed across the sea. Luigi raced to the coast with Gloom and Joy following him. He waved out to them."Guys!"

When Mario and the others landed on shore, they celebrated. "LUIGI, YOU'RE SAFE," DK squealed.

Luigi flinched away from him. "Ah, I don't wanna be covered in paint, especially not pink!"

"Oh relax; it won't stick," he said bearhugging Luigi, and lifting him.

"Thanks, Donkey Kong; I'd be more than happy to help, but please a' stop crushing my spine."

"Okay," he said letting go.

"Who are those guys?" Mario asked referring to the hearts. At that moment, a red one and a green one appeared before them.

Joy cheered for Mario, "It's you! The one who Peach likes!"

All four hearts began to orbit around Mario. "What's a' going on?"

"We are bestowing you with special powers-ones of wind, water, fire, and healing."

Luigi introduced the Vibes to his friends; "Guys, this is Gloom, Joy, and um..."

"Calm," the green Vibe introduced, "and the red one is Rage."

Mario didn't sound pleased. "Am I a' gonna have to cry every time I wanna splash some water around?"

"Not at all, silly," Joy beamed.

Mario gave a huge sigh of relief.

Gloom noticed DK and Toad's unusual appearance. "Great criminy. His plan already in place."

Everyone gave a collective "Huh?"

"From what I know, when soaked with one of those, you only feel one emotion, leading to your downfall. The Toad is calm, and the gorilla is afflicted with Love."

"What's so bad about that?" Toad asked, "I mean, I feel brave and I'm still kind." Everyone gave him a blank stare.

Mario broke the silence saying, "You might have a point; also, Yoshi's tongue is black-that's not normal. It was really mean to us, so we covered his mouth with an old flag from the port."

"Black?! That's the worst one of all-it turns the covered organism evil."

"EVIL?!" everyone screamed.

"Yes."

"Are there any ways to a' diffuse it?" a concerned Mario appealed.

Calm said to them, "Either with the Vibe Scepter or one of the secret ways."

Tell us, please!"

"Can't. An ancient Vibe pact states that it is forbidden we discuss them with other Vibes in order to keep emotional balance," Rage stated.

"Then we're just gonna have to find them ourselves."

"Speaking of finding things and people, where's Wario?" Donkey Kong asked.

Luigi pointed in the direction Wario had left in; "He went a' that way towards Bowser...without me."

"Well, what are we waiting for?" The group rushed along the path, hoping to catch up to their greedy friend.
