Hey guys! First I gotta say that I know that I left you all guys hanging waiting for me to upload the next chapter, and I'm so sorry for that. I've been having problems at my house lately. My brother's dad kept bothering me, my sisters and my mom . God he's annoying. I don't even know how my mom liked him first. *shivers*. Okay! So, yeah, here's the fourth chapter for my so called 'How to survive the Zombie Apocalypse' story. My... great... story? I don't even know if people like my story anymore 'cause I only got about 6 reviews for the third chapter and that... frustrates me? I don't even know how I feel about besides feeling disappointed with myself, for not trying hard as I did on the third one like I did on the first two (even though it was the longest chapter I have EVER written). But I promise that THIS chapter will be a bit better. I said a BIT, so don't expect it to be all awesome with the detais and everything. But I gotta say that I'm not gonna stop updating this story (like I did with my first story published in fanfiction). That's all I gotta say besides I don't own the movie, series, books (there will be two characters from the books. If you guys know, review or PM me ;)), and everything with HTTYD.

Chapter 4 arrived! Please read and hope you guys enjoy! :D

Previously on Chapter 3:

...then, something else entered his mind.

"Wait," he said and they looked at him. With terrafied eyes he said, "Where's Astrid and Tuffnut?

Narrator's POV

All of a sudden we see one of those crazy people ran towards a door where a bunch like him are banging or hitting at some double doors on a building next to the school and try to open the doors to get to some persons that are inside. All of the crazy have wrinkled green or grayish face, they were missing parts of their body parts or they had holes or huge cuts, blood seeping out of it; they had ugly fingernails, which they used to scratch the doors. Also their clothes were all ripped open from the bites and were covered with blood. They furiously shrieked as moee of them piled up next to the ones at the door outside of the building. There were teachers, students, councelors. All the people from the school.

Inside, where all the healthy people were, Astrid and Tuffnut were among them, blocking the doors with all the Gym supplies they could find.

Tuffnut had Gym class before all of that happened, he was going to go to his next class ( not before doing a small prank to the gym teacher for the first day of school, of course). Astrids' class was Gym, she somehow managed to get to the Gym quickly enough.

So now both were at the same place and doing the same thing Hiccup, Ruffnut, and Fishlegs were doing, but with help, obviously. But their luck were not the same as the other three, the crazy people didn't went away, they just kept increasing making it hard for all the people blocking the doors.

Astrid's POV

Tuffnut and I were blocking the doors with the other people so those crazy people won't get in and do the same they did to the other people to us. Hell no am I going to let that happen to me or him even if it scared the hell out of me when I saw those crazy people eating our teachers and classmates. I feel sorry for the freshmen kids for having their first year of school like this. And I expected my senior year to be great, now that Hen- I mean Hiccup, is our friend.

All of a sudden we hear the door hinges creak, meaning that the door hinges were starting to break lose. Trying to control my panic, I told the others, "Everybody, we need to find an exit right away. These doors won't hold for much longer." Tuffnut looked at me and started looking everywhere for something. Probably an exit, but there's a chance that those things might be waiting for us there too.

But what he said was something I didn't thought he would use as an idea:

"There's an open vent in one of the coaches offices. It's wide enough for us to go through it and get out of here before those things enter" he said as he pointed towards where the coaches offices are.

Sighing in relief I told him, "Tuffnut, if it weren't for you not taking a shower regularly, I could kiss you right now."

He smiled saying, "I'm trying to break a record."

I rolled my eyes. Even in a situation like this he's still able to make jokes.

Again, the door hinger creaked, but this time it made the door open an inch. People saw this and some started to scream or began to back up terrafied.

"Okay! Everyone calm down." Turning to Tuffnut I said, "Tell us where that vent is."

He nodded and shouted, "Okay, everyone follow me! Let's get out of here!"

"Wait! Somebody gotta stay here to keep the doors blocked until all of us get out of here." A familiar and irritating voice said among all the people.

Groaning, I turned to: "Snotlout, no one will stay here and sacrifice themselves just so we can get out." I told him.

But then a boy, probably a freshman cause he was using a t-shirt the freshmans use, said, "I'll stay."

Shocked at his answer, I told him, "No. No one is going to stay-"

"No one tells me what to do." He said sternly, interrupting me. He added, "I will stay and no one's gonna change my mind."

"B-but why?" a girl who was next to him asked. Based on their appearance I think both are twins. Both had black hair and brown eyes.

The boy turned to the girl and with a small smile told her, "I don't want to put you in danger too."

"What do you mean?" I asked him. Then it hit me, he... he's-

"I got bit by one of those things," he replied and lifted his pant leg, showing a bite that was starting to swell up and it had a green color.

His sister gasped at it and tears started to filll on her eyes. "No," she told him, "You're not staying."

The boy then grabbed her shoulders and with a gentle voice told her while looking at her eyes. "I have to. 'Cause if I turn into one of them, I won't have power of myself and that'll put YOU in danger. And that's something I don't want to happen."

The girl was now crying and was shaking her head furiously at him as she muttered, "But you promised to be my side everytime. You can't leave me now! Not now, Sam!"

The boy, Sam, pulled her towards him and hugged her. "You have to," he told her and added, "Come on , Sarah, you can do this. Be strong. At least do it for me, survive this zombie apocalypse for me. I'll be very proud of you "

Zombie apocalypse? What the hell did he meant by that?

Sarah looked at him and with a small smile nodded. "Okay, I'll be strong for you. That's what twins do right?"

"We do?" I heard Tuffnut mutter to himself, making me roll my eyes.

A bang was suddenly heard. The hinges had already broken loose. People started screaming. Lifting my arms, I shouted to everyone, "Everyone, follow him, " I gestured at Tuffnut, "he'll take you out of here."

"How?" a boy asked.

"Just follow me," Tuffnut told him and started running towards where the offices where. "Come on!"

Everyone followed him, some pushing people out of their way. I turned to the boy, Sam, and said, "When were you bitten?" He looked at me and replied, "Way before everyone knew about this. About 30 minutes or 1 hour ago. I was one of the first people who witnessed the beginning of this"

The few people who were helping block the doors left, except for some 6 more people. They saw my puzzled expression, so a girl told me, "All of us were bitten, too. We didn't say anything cause then it'll worry the rest of the others." Everyone nodded.

Before I could say anything, another bang was heard and the door opened about an inch wide.

"Go!" Sam told me.

"If people ask for us, tell them the truth for us, will ya?" A junior boy asked me. I nodded as I backed away slowly. But before I began to ran towards Tuffnut and the others, I turned to Sam saying him, "Wait. You mentioned something about a 'zombie apocalypse'. What does that mean?"

He smirked and said, "Ask my sister. Believe it or not, she knows more about it than I do."

A girl pushed me back saying, "Now go, or the things will get you too."

I glanced back at them and managed to say two words I usually never say to people, "Thank you," I turned around and began to run towards where Tuffnut was waiting for me at the offices.

Stopping to a halt, I closed the door of the office and stood next to him. He had moved the desk and place a chair on top of it so everyone could get up. I asked him, "Has everyone went through already?" He nodded. "Okay, you go first and then you'll pull me up." Nodding, he said, "Sure thing, Astrid."

When he was up, he lowered his arms towards me. "All right, your turn."

As I climbed the desk they used to get up there and started to reach him, the both of us suddenly heard a loud crash and screams after that. My eyes widened as I knew what had happened. "Come on!" Tuffnut exclaimed as he gestured his hands, meaning to grab them so he can pull me up. I got on my tip toes and stretched my arms, but realized that I couldn't reach. Damn! Curse my shortiness.

"I... I can't reach," I told him as I stretched my arms and hands as far as I could, only to manage to brush his fingertips. I heard him tell someone who was next to him to help him get more lower.

He extended his arms towards me as far as he could and said, "Yes you can, Astrid. Just stretch yourself more. You can do it, girl."

I tried again standing on my tip toes and stretched as far I could go and before I could do anything, the door of the office started to make a banging noise. "They're here." I screeched. Turning towards Tuffnut, I began to extend my arms again. "Come on... come on," I muttered to myself.

And right when I managed to make a jump and grab his hands, the 'zombies' managed to break the door and enter the room. "Pull me up! Pull me up!" I half screeched and half exclaimed terrafied. Tuffnut lifted his arms and with the help of the people next to him, managed to pull him back, making him to pull me up more faster. I looked down and saw them crashing and breaking things. But then one of them saw me and she suddenly extended her arms and unexpectedly grabbed my ankle. I gasped and by instinct kicked her in the face with my free foot. The force of the kick made her let go of me and fall to the ground flat on her back. Screeching angrily, she got up and tried to grab me again but I had already been pulled up by Tuffnut.

The first thing I did was to look at my leg where she had grabbed me. "Give me some light," I told Tuffnut between the screams and screeches from the things below us. Tuffnut obeyed and took out his cellphone. Illuminating my ankle, I let out a my breath, relieved. There was no scratch or ripped cloth in my leggings.

Tuffnut put his cellphone back in his shorts pocket and grabbed my arm saying, "We gotta get out of here. Come on."

Nodding, I followed him and the rest. What bothered me was that it was dark in here, with only smal light from the vent we entered. "I hope you know how to get out of here," I told him.

Chuckling, he told me, "There's a first time for everything, right?"

Glaring at him, I punched him in the side. I heard him groan and whisper, "You took the breath out of my lungs." And crouched more to grab his side. I just smiled at it while I thought, That's what you get.

Then my cellphone rang.

Hiccups POV

Ruffnut and Fishlegs gasped when I asked them that.

I started to pace back and forth, both of my hands grabbing locks of my hair furiously as I tried to think of something. Both of them just stared at me, which made me feel more desperate than I already was. After a minute I remembered that we have something that communicates us with everyone. "Cellphones!" I exclaimed at them all of a sudden, making Fishlegs jump. "We can call both of them and see if they're okay."

Ruffnut facepalmed herself and said, "Duh, we're so stupid. I forgot about the technology that we already have now."

"I'll give you Astrids' number so you can call her, " Fishlegs told me.

"Why?" I asked him.

"I'll get all nervous if I tell her." He told me sheepishly.

Rolling my eyes I took out my cellphone. "What's her number?"

After he gave it to me, I touched the 'call' button and put my cellphone against my ear. One ring... two rings... three rings... and right before I tought she wouldn't anwser, she picked up.

"Hello?"

"Astrid!" I exclaimed as I sighed in relief, not bothering to hide my happiness for hearing her voice.

"Hiccup? Is that you?" she asked. I could hear noises on the background, which made me worried."How did you get my number?"

"Yes, it's me, Astrid. And Fishlegs gave me your number. Is everything alright? I hear noises on the background. Are YOU alright? Are you hurt? Is Tuffnut with you?" I asked, my concern taking over as I talked.

"Hiccup, calm down. Everythings fine... well, now it is..."

"What do you mean by that?" I asked her. What had happened before I called her? Was Tuffnut hurt?

I heard her sigh and she said, "Those... things. They almost got me and Tuffnut. He's okay. We managed to get away from them by climbing to a vent in one of the coaches offices. It... one of them grabbed my ankle, but I managed to kick her in the face and got free from her."

I nodded to myself and told her, "The good thing is that you're okay. Ruffnut and Fishlegs are with me. They're also okay. The three of us managed to escape from them by entering a class and blocking the doors. Luckily they left."

"Well Tuffnut and I gotta help the rest of the people to get out of this vent and find a way outside, or somewhere safe enough for us to get out." She told me.

"Okay, so-" I didn't get to finish my sentence when Ruffnut suddenly took away my cellphone out of my hand. I turned to her with an annoyed look. Seing this, she told me, "What? I need to talk to her too."

I rolled my eyes and walked towards Fishlegs, who was sitting on the floor again with his head between his legs.

I flopped down beside him and sighed. "So..." I started, catching his attention as he lifted his head to look at me. "...how are you handling this, 'Legs?"

"I... I don't really know. I'm just shocked at what's happening right now... or... what happened a while ago," he sighed and looked at me. "Look, I'm sorry about-"

"No..." I said, cutting him off as I lifted my arms in front of him, signaling him to stop. "I'M the one who's supposed to apologize for that. I got a little carried away there. I'm sorry, Fishlegs."

He stared at me and for a few seconds, he smiled and said, "Apology accepted." Then he extended his hand out. Smiling, I extended mine too and we shook hands and hit our chests together while pating our backs with a small chuckle.

"You two finished making up?" Ruffnut said to us as she stood in front of us, a hand on her hip and then she threw my cellphone towards me. I caught it easily and put it in my pants pocket as I got up.

"We're finished, " Fishlegs told her as he got up too and then crossed his arms.

"So, what do we do, Hiccup? How are we going to get out?" Ruffnut asked me.

"I would know if I could of talked to Astrid and see where could all of us meet together on one place, buy you took my phone away right when I was going to ask her that," I told her as I crossed my arms and looked at her with an annoyed look.

She snorted and said, "Well sorry. But I already talked to her about that and she said that she and my stupid brother will try to go to the front of the school. I told her that we'll meet them there."

I just stared at her with surprise and she just said, "What?"

Shaking my head, I told both of them, "Okay, I've been thinking on a plan on how to get out of here safely. But first I'll need both of your support."

Ruffnut nodded and Fishlegs said, "You can count on us."

"Yeah, just tell us what we have to do and we'll do it," Ruffnut added with a smirk.

Nodding at them, I said, "Okay then, let's get started," I went towards a desk and sat on it. "First things first: we'll need weapons to defend ourselves from those things. Which, by the way, are called zombies."

"'Zombies'? That's what those things are called?" Fishlegs asked.

"Yes. Haven't you guys seen zombie movies?" I asked. They looked at each other, then at me, and shook their heads with a confused expression. "Have you guys seen the movie 'Night of the Living Dead'? A movie called 'World War Z'? Where Brad Pitt comes out?" Again, they shook their heads. "'28 Days Later'?" Again... they shook their head. For last, I asked irritated, "At least played games? Like 'The last of Us'?" They shook their heads again! Man, where have they been watching all their years?

"I don't have any idea what you're talking about." Ruffnut told me and Fishlegs nodded, agreeing with her.

I groaned and facepalmed myself and said as I clasped my hands together, "Guess I'll have to give a small lecture about what 'zombies' are, what they do and what can they do to you." I took a deep breath and began, "'Zombies' are dead living people who eats live human flesh to survive. Like I said, they're already dead-"

"But how can they still be able to walk?" Ruffnut asked me. Fishlegs was just listening every word I was saying. Like hearing a new lecture he has never heard and wants to learn more about it. Which I think he will want to.

"They're able to walk because they're kind of infected people-"

"Like a virus?" Fishlegs asked.

I nodded. "Like a virus," I said. He smiled, as if he had asserted a correct answer on a question on a class. "So when the virus gets inside a person, it spreads out all over your body system until it gets to your brain, which will then start to die, or rot, and will be filled with the virus. Your body will begin to rot, and the brain will die but will be filled with the virus creating a living virus that can make you turn into those things.

"What about the heart?" asked Fishlegs.

"It'll die, too. Like I already said, the virus is what keeps the human body to keep moving, even without a heart. The virus will turn the people who are infected into those things the three of us saw earlier. They will not be able to think straight, they won't care if they're eating their family members, friends, teachers, whoever. The only thing they look for is FOOD. And I'm pretty sure you guys know what type of food I'm talking about. " The two nodded. Fishlegs looked like he was about to pale and faint and Ruffnut had a terrafied expression.

"They ways a people can turn into one of them is by a scratch, bite, or saliva/blood contact on one of your cuts by them."

Ruffnut placed a hand on her chin and, cautiously, said, "So what you're trying to say is: they turn into infected human eating flesh people who can't turn back to normal once they're bitten?"

"Yeah," I said, glad that I won't need to explain it for the second time. "That's exactly what I'm talking about."

"Now that you've told us about the 'zombies'... how are we going to get some weapons and get out safely? We're in a biology class, you know that right?" Fishlegs told me.

I smirked at them and said, "Yeah. Which means that there is some bunsen burners, glass, acid bottles... you know what I mean." Ruffnur just looked at me bewildered, while Fishlegs' expression soon turned like mine and said while wiggling a finger at me, "Ohhh... I see where you're going. Good idea."

"Okay, what are you two talking about? I don't understand anything." Ruffnut exclaimed as she glared at us.

Turning to her, I smiled devilishly as I said, "We're gonna make ourselfs some explosives."

"What about weapons?" she asked, but I could tell she was getting excited too.

"Weapons too." I answered.

"Cool ones?"

Sighing, I answered, "Yes, 'Ruff, cool ones."

She threw her arms up in the air with a small 'yes!'

And here I thought she was the normal one from her and Tuffnut.

Yes! Chapter 4 finished xD . Hehe, okay... so yeah, Hiccup, Ruffnut and Fishlegs are going to make themselves some cool weapons and explosives. *devilish smile* I wish I could do that too. If there was a zombie apocalypse for reals here I our world... it'll be awesome. But... I think I won't survive long enough xD. I guess that for some of you are like 'really? Explosives inside a school building?' Or some might be like, 'awsome!' But who would'nt wanna do that to a school? Even if it were the only 'alternative' on a situation they're in right now.

So!

For Astrid and Tuffnut, yeah, they'll try to get out of the vents without the zombies and protect the people who are with the two of them. Even Snotlout's sorry ass xD.

I hope you guys enjoyed this chapter. Chapter 5 will be published next week. I PROMISE you guys that it's for real this time. I'm already working on the chapter :)

So... oh! About the chapter about where the characters appearances and history and more about them.

It is still in progress. I'm having difficulties on the choice of clothes for each of them. Also for what type of weapons (guns, melees...) each should have. I'm asking all of you guys a favor about giving me choices of type of clothes they could wear later on in the story. Also to give me options for different types of guns (small, medium, big) and melees (crowbars, baseball bats...). I'll appreciate it SO much if you guys helped me with that :). PM me if you guys have some ideas

That will be all except for:

Read and review PLEEASEEEE ^.^
