In a commercial the trio are watching there's a temple and a volcano behind it. "Thousands of years ago, in the most ancient of dojos, the most delicious sandwich in the world entered our realm." The sandwich flies out of the volcano and a man on a sidewalk catches it and eats it. "The only problem is if you eat it wrong... You'll die." The announcer said. "Huh?" The man asked. The man explodes. Then the scene cuts to a shirtless man holding the sandwich. "Fortunately, men discovered the correct way to eat it." The man's pants get ripped into jean shorts and a mullet wig appears on his head. "With cut-off jean shorts and the proper haircut."

The man holds the sandwich up, then the scene cuts to a montage of random guys with jean shorts and mullets eating the sandwich in different ways. "Death Sandwich! Death Sandwich! If you don't eat it right, you're gonna DIE tonight! It's the Death Sandwi-i-i-i-i-i-ich!! So come on down to "Death-Kwon-Do Pizza & Subs." The announcer then points to the camera. "And remember, eat it right or you'll die!" He shouted. The trio look at each other and run out the door; they go to the "Death-Kwon-Do Pizza & Subs" in the Two Peaks Mall; (Y/n), Mordecai and Rigby run to the counter.

"Uhh..." the trio said. The Sensai turns around, wearing an apron and is holding a notepad and pen. "How may I help you?" He notices Mordecai and Rigby. "You guys?!" He asked. "Haha, hey." Mordecai said. "So, you have the nerve to look me in the eye after nearly destroying my Death-Kwon-Do business?!" The Sensai asked. "What did you guys do?" (Y/n) asked, crossing her arms. Rigby chuckles nervously. "Uh... we stole pages from his book." Rigby said. "Oh..." (Y/n) said. "Look, we're sorry about that, man. But hey, it looks like you really bounced back.

Got this whole sandwich gig going on, looking good." Mordecai said. The Sensai sighs. "You're lucky forgiveness is one of the many virtues of Death-Kwon-Do. So what can I get you?" He asked. "The Death Sandwich!" The trio said. "To receive the Death Sandwich, you must first sign this waiver of death." The Sensai said. "Yeah, sure. Let's do it." Mordecai said. "Why not?" Rigby asked. "Okay." (Y/n) said. Sensai shows the waiver saying "You can't sue me" and (Y/n) scoffs.

"Of course." She said, she and her friends sign it. "Alright, I'll have that out for you in a minute." The Sensai backflips to behind a table and makes the Death Sandwich and making noises at the same time; the Sensai puts his hands together and brings it to (Y/n), Mordecai and Rigby. "One Death Sandwich." He said. "Yeah-yuh!" The trio said. "But, remember. If you don't eat it right, you die." The Sensai said. "Yeah, yeah. Wear mullets and jean shorts. We got it." Rigby said. "We did watch the commercial." (Y/n) said. Mordecai grabs the sandwich. Later the trio are in the kitchen in Pops' house. "Man, I'm about to tear this thing up!" Rigby said. (Y/n), Mordecai and Rigby laugh as they open it.

"Whoa, wait. We gotta get mullets and cut-offs first." (Y/n) said. "Aw, yeah, yeah, yeah. Now you're talking lunch!" Rigby said. "Death Sandwich! Death Sandwich! Death Sandwich!" (Y/n), Mordecai and Rigby leave the sandwich on the table and walkout of the kitchen; Benson walks in, whistling and sees the sandwich on the table. "Well, well, well. Looks like it's time for a little payback. Let's see how they like it when somebody else steals their sandwich." Benson takes a bite of the sandwich. (Y/n), Mordecai and Rigby enter the kitchen wearing mullets and cut-off jean shorts.

"Death Sandwich! Death Sandwich!" The trio shouted. "Aw, what?" Rigby asked. "Benson!" (Y/n) shouted worriedly. Benson coughs. He has turned green in the face and is choking and gagging. "Whoa, are you alright?" (Y/n) asked worriedly. "It really is a death sandwich." Rigby said. "Death sandwich? Why would you buy something that kills people?" Benson asked. "It doesn't if you eat it the right way!" (Y/n) shot back. "Why would you eat somebody's sandwich!?" Rigby asked. "Come on, guys. This is serious. We gotta get Benson a cure from the Death Sandwich before it's too late." Mordecai said. The quartet go back to the Death-Kwon-Do Pizza & Subs.

"Dude, you gotta help us. Our boss ate the Death Sandwich wrong." (Y/n) said. "What? How could this have happened?" The Sensai asked. "We left it in the kitchen, and Benson came and ate it." Rigby said. The Sensai groans. "It is clearly stated in the waiver that the Sandwich should never be left unaccompanied under any circumstances!" The Sensai said. "You didn't read the waiver? That's a bit out of character for you, (Y/n)." Benson said.

"Now, if you would excuse me, I have a business to conduct. Good day, gentlemen." The Sensai said. "But our boss is gonna die!" Rigby said. "Yeah! Have a heart, huh?" (Y/n) asked angrily. "If the Sandwich is so dangerous, then why don't you just take me to the hospital?" Benson asked. "Yeah, you're probably right. Let's get outta here." Mordecai said, and the Sensai groans. "I'm afraid that would be a fatal mistake." They all stop, then turn around.

"Your boss is now far beyond the help of Western medicine." He said. "What?!" (Y/n) asked. "Well, then, what are we supposed to do?" Rigby asked. "His only chance of survival now is to see my Sensei, the Grand Master of Death-Kwon-Do. He is the protector of the Sandwich of Life." The Sensai said. "What's the Sandwich of Life?" (Y/n) asked. "It is the only known cure for the Death Sandwich.

He will listen to your request, and if he agrees, he will let Benson have a taste. One bite from the sandwich will cure him instantly." The Sensai said. "All right, let's do this. What's his address?" Mordecai asked. "I'm afraid it is not that simple. No mere outsider is allowed before the Sensei. I must accompany you on your journey. But time is of the essence. If your boss does not take a bite from the Sandwich of Life within six hours, he will die."

The Sensei said. (Y/n), Mordecai, Rigby, and Benson have a disturbed look on their faces. Sensai flips the sign around to say, "Be back in 5 minutes of death." He then drives off. In the car, Benson is choking and gagging. "Benson!" (Y/n) shouted as she quickly runs over to him. "What's gonna happen to him if we can't get the Sandwich of life in six hours?" She asked worriedly. "His body will undergo six stages of agony while speeding towards his inevitable death. His face will turn green and he'll begin to choke." The Sensai said. "That's what was happening to him in the kitchen!" Rigby shouted.

"Yes. Soon after, his face will start to burn." The Sensai said. "Oww! It burns!" Benson shouted. "Benson's intestines will begin to melt and leak out of his body." Rigby scoots away from Benson. "He will shriek in pain, but no one will hear it, because his vocal chords will have long since evaporated. But then he'll regain his vocal chords.. ...Only to cry out for mercy in ancient dialects long since forgotten." (Y/n) covers her ears. "Okay I've heard enough!" She said. "Well you asked." The Sensai said.

"I'm pretty sure you can go 65 here." Benson said. Finally, the car stops at a temple nestled in the mountainside. "I'm gonna go request a meeting with the Sensei. You guys just wait here." He exits the car. He approaches the guards at the temple gates, but one of them punches him, knocking him down. "Okay, minor setback. I forgot to mention that me and the Sensei kind of had a falling out." He drives away.

"You call that minor?!" (Y/n) asked angrily. "It's time for Plan B." The Sensai said. "What's Plan B?" Mordecai asked. The Sensai pens the trunk. "We sneak in and take the sandwich by force. Here, Benson. You're gonna need the power of Death-Kwon-Do." He tosses a pair of cut-off jeans to Benson. "What, I just have to put these on?" Benson asked. "Not quite." He pulls out a razor, and then turns it on. Sensai and the four park workers all have cut-off pants on.

They all leap over a wall. "The Sandwich of Life is at the very top of the mountain. Come now. We move as one!" They all run for the entrance, but one of the guards spots them. "Hey, stop!" The guard rings the warning bell. "Quickly! Into the first chamber!" They enter the temple and find themselves in a room with a pit filled with rows upon rows of thick bamboo poles. Paintings of tigers and cranes are on the walls. "Things will become increasingly more difficult as we approach the sandwich. Be ready." The Sensai said. On the other side of the pit, three guards enter the room, each carrying a bladed weapon. The middle one steps forward.

The guard lets out an attack yell. "...I mean Step of Dea-a-a-a-a-aa-ath!" He plummets to his doom. "Wha...?" (Y/n) asked. "That reminds me. In this room, you must say, "Step of Death" every time you step, or you will plummet to your death. Almost slipped my mind." The remaining two guards start hopping from pole to pole, saying... "Step of Death! Step of Death! Step of Death!" "Step of Death!" (Y/n), Mordecai and Rigby said. "Step of Death!" A guard shouted. "Step of Death!"

(Y/n), Mordecai and Rigby use a Death Punch on the guard. "Step of Death! Step of Death!" The Sensai and Benson said. The final Guard leaps in the air, swinging his weapon violently. Sensai and Benson dodges out of the way. "Step of Death!" A guard shouted. The Sensai does a Death Kick. "Step of Death!" He shouted. Rigby does a Death Flip on another guard. "Step of Death!" He shouted. Benson then Death Kicks the guard. "Step of De-e-e-eath!" Benson said weakly.

"Step of Death!" (Y/n) does a death punch on another guard. The group go through the next couple of chambers. The second one has a bunch of guards carrying sickles who jump out of the trees. The group defeats them. In the third chamber, a bunch of guards riding motorcycles crash through the windows.

They circle the group, whirling their meteor hammers. But the group uses their own weapons against them. Just as the group approaches the next set of doors, clouds of mist appear out of nowhere. Guards wielding sais attack them, but to no avail. Inside the fourth chamber, two guards slam the ground with their powerful axes, knocking everyone backwards. (Y/n), Mordecai and Rigby do a Death Jump and take out both of them. In the fifth chamber is a guard with clawed hands and wearing a hockey mask. The guard crosses his arms and multiplies before the group.

But the guard and his duplicates are no match for the group. Finally, the group approaches the mountain summit. By this time, however, Benson has grown very weak, and is now pleading in ancient dialects long forgotten. "Agga dagga dume tu kara tu..." Benson said. "Come on, hang in there, Benson." (Y/n) said. "She's right. We're almost to the top, Benson. Don't give up yet." Mordecai said.

The Sensei is through that door. The door opens to reveal the Grand Sensei floating above the tip of the mountain's summit. Two sandwiches are next to him. "Is that your Sensei?" (Y/n) asked. "Yes. And that sandwich right there is the Sandwich of Life." The Sensai said. "Which one? There's two of them." Rigby asked. "It's on the organic multi-grain. Opposite, we have the deadliest sandwich known to man: the Double Death Sandwich." The Sensai said.

"Whoooooaaa..." the trio said. "Just let me address the Sensei. He might still be mad at me." The Sensai said. They all approach the Sensei. (Y/n) lays a weakened Benson down gently. "Sensei..." the Sensai said. "You got a lot of nerve coming back here after what you pulled." The Sensai's master said. "Forgive me, Sensei..." the Sensai said. "What did you do?" Rigby asked, and the Sensai groans. "I took him off the streets and raised him like my own son. He repaid me by stealing the recipe for the Death Sandwich and mass-producing without permission!"

The Sensai's master said. "I will accept full responsibility for my crimes against the school. But there is now a more pressing matter at hand. Our friend Benson is about to die from eating the Death Sandwich incorrectly. We humbly request that you bestow the Sandwich of Life upon him." The Sensai said. "You must be a real fool. Did you honestly think I'd just hand over the Sandwich of Life? Kill them!" Several guards wielding katanas jump in the air and land in front of the group. (Y/n), Mordecai and Rigby jump and avoid their katanas, but get captured. "You don't deserve the powers of Death-Kwon-Do!

The Grand Sensei spins a razor in the air and hurls it forth. Sensai yells "Noooo!", and manages to escape the guards' clutches and jumps to the ground just as the razor shaves off some of his hair. (Y/n), Mordecai and Rigby scream in anger and Death Flip, knocking the guards backwards. Then the Grand Sensei laughs wickedly as his outfit comes off to reveal a pair of cut-offs and wristbands. He takes the two sticks from his hairdo and lets it slowly unfold.

As (Y/n), Mordecai and Rigby stare at their foe and the Double Death Sandwich, Sensai looks on. The Grand Sensei then hurls the sticks at (Y/n), Mordecai and Rigby, but the trio dodge out of the way, and the sticks hit the doorway instead. "Yaaa! " They start fighting the Grand Sensei. But the Grand Sensei has the upper hand and lands multiple blows while also blocking their attacks.

"Yaaa!" The trio start fighting the Grand Sensei. But the Grand Sensei has the upper hand and lands multiple blows while also blocking their attacks. "Agga dagga..." Benson coughs. "Sanoubi..." he said. The Sensai's master laughs. "He says that he forgives you. It's too bad he'll never taste from the Sandwich of Life." He removes the cover from the Double Death Sandwich.

"Sensei, no! Not the Double Death Sandwich!" The Sensai shouted. "Order up!" With an attack yell, he sends the Double Death Sandwich flying forward. Sensai plays a few notes on his flute. He hands a small scrap of folded paper to a yellow bird, which hands it to (Y/n), Mordecai and Rigby. They unfold the sheet of paper and look at it. The trio gasp. "The Bicycle Kick of Death!" The Double Death Sandwich gets much closer. "Now!" (Y/n) said. She and her best friends do the Bicycle Kick of Death, deflecting the Double Death Sandwich.

The sandwich flies smack into the Grand Sensei's mouth, killing him. Rigby then removes the cover from the Sandwich of Life and tosses it to Sensai, who feeds it to Benson. "Come on..." Benson is cured instantaneously, just as the mountain starts to rumble. A deep crevice suddenly appears on the ground. "What's happening?" Rigby asked. "The mountain is self-destructing!" The group falls through as the ground crumbles beneath them.

"Use the Death Jump!" The group uses a piece of crumbling earth as a boost and jump out of the crevice. They all land safely in the car and start driving speedily as the mountain collapses behind them. Once they are safe, they all breathe a sigh of relief. "Thanks so much. I don't know how we can ever repay you." (Y/n) said gratefully. "I'll probably think of something." The Sensai said. Later the trio are on a commercial for the Death Sandwich. "So come on down to "Death-Kwon-Do Pizza & Subs" at the Two Pines Mall. And remember..." the trio point at the camera. "Eat it right, or you die!" They said. Muscle Man and High-Five Ghost are watching the TV. They dash out the door.
