Applejack, Rarity, Rainbow Dash and the CMC went throughout town selling the cookie boxes to each person in each house. They paid them each dollar for the cookies and each given enough credit. But Rainbow Dash was too busy thinking about the prank.
Later that night, they were finally done with the delivery. They were all tired, except for Rainbow Dash.
"I think you three should be real proud. Y'all did a mighty impressive job for your first go-'round." Applejack proudly said.
"You took the words right out of my mouth, Applejack. Isn't that right, Rainbow Dash?" Rarity turned to her.
"Any minute now." She said quietly.
"Uh... "any minute now" what?" Applejack asked.
"Huh? Oh, uh, nothing! Have you guys noticed how quiet it's gotten? I mean, it's still early, right?"
"Of course it's quiet. People can't talk while they're eating those fabulous cookies, heh."
"You think?"
"Of course. They're probably all in a cookie coma right now."
"Huh... Maybe you're right. I'll go check."
Rainbow Dash walked around the town and everything was still quiet. She heard no screaming or anything.
What is going on...?"
She looked into someone's window and saw no one is there.
Okay. Definite cookie-eating happening. But... where is everybody? They must have seen their rainbow mouths by now... They should all be running out into the streets! Unless everybody went to bed early..."
She decided to go to Pinkie's house.
She knocked on Pinkie's door, but there was no answer. She decided to go to Sugarcube Corner.
When she got there, there was nobody there. She then stepped on something gooey and crunchy, she saw that it was one of her joke cookies.
"The whole town got the cookies, and now everybody is shut up in their houses! You don't think there's something wrong with the joke cookies, do you?" She asked herself.
Then she turned to see Mrs. Cakes.
"Mrs. Cake! Phew! Have you seen Pinkie? I was thinking might have something to do with her not feeling great."
All she could heard was chewing and husky breathing.
"Uh... Mrs... Cake...?"
Rainbow reached to touch her, then..."
"Cookies...! Cookies!
It turns out she looked raspy like a zombie.
"Uh, I can see you're busy! I'll come back!" Rainbow whimpered and ran off.
She bumped right into a caboard which opened and revealed Pinkie in it.
"COOKIES...!"
She was a raspy too.
Rainbow screamed, then she heard burbling which came from the babies, Pound Cake and Pumpkin Cake.
Rainbow was frightened, this night was supposed to be where the prank is supposed to happen. But instead it's a night of cookie craving zombies.
Rainbow Dash used her speed from her geode and raced out of Sugarcube Corner. As she stopped she looked around and saw that everyone in town has turned to zombies as well. Rainbow Dash was scared and confused, she didn't know what to do. All she could do was run for her life.
She ran into more people who were students of CHS who are now zombies. She ran into Twilight and Spike.
"Twilight!" She panted. "You gotta come with me to Sugarcube Corner! Something's going on with the Cakes! Well, not something exactly. I mean, it may have something to do with these joke cookies..."
But then...
"Cooooooookies..."
It looks like Twilight and Spike are zombies too.
Rainbow Dash then rushed to Sunset Shimmer's apartment building and busted right in her home and saw her sitting on her couch with her TV screen on.
"Sunset, I need your help. Something's gotten into everyone in town. It's looks like everyone are zombies."
Sunset didn't respond.
"No...please don't tell..."
"Cooookies!"
Sunset Shimmer was a zombie too.
Rainbow ran out of the apartment building, what is she gonna do now?
"What am I supposed to do now?" She asked herself. "Everyone in town are zombies and it's all because of these stupid joke cookies. If only I had help."
The she remembered something, she picked up her phone and dialed Soarin's number.
Soarin's phone rang.
"Hello?"
"Soarin, it's me, Rainbow Dash. Get the rest of the Wonderbolts down here as soon as possible!" She called.
"What do you mean?" He asked. "What's going on?"
"I'll explain that later! Just get the rest of the team down here!"
Where should we meet you"
"At the Rarity's house. Hurry!"
She hung up and hurried to Rarity's house.
She ran into more zombies, including her own best friend...Fluttershy!
Later, Rarity gave Applejack and Applebloom an invitation to her house.
"You sure you don't mind us all comin' over?" Applejack asked
"Oh, of course not." Rarity replied. "I think the girls have earned a little celebration for all of their hard work. And I have plenty of sewing machine cake left over. Unless anypony wants a cookie...?
"Don't touch those!" Rainbow Dash came right on time and kicked the cookie box right out of Rarity's hands.
"Oh! There is certainly no call for that! There's plenty for everypony."
Right on the nick of time, Soarin and the rest of the Wondercolt's showed up in his car.
"Rainbow Dash, you said you wanted to meet us here?" Soarin called.
"Meet you here? What's going on here?" Applejack asked.
"I'll explain later, Come on! We gotta get outta here!"
"Come on! We gotta get outta here!"
"There's no time! You have to follow me!"
"Oh, Rainbow Dash, if you want all of those cookies, you will have to buy them, just like everypony else."
"I don't want the cookies—But they do!" She pointed to the zombies.
"Wh-wh-what... What's happening?" Rarity sounded horrified
"I'll explain later. Come on!" Rainbow said as she lead them to Applejack's truck.
Applejack drove out forward to the road and The Wondercolts followed along.
They drove all the way from the neighborhood to the city.
"We need to find somewhere to hide!" Sweetie Belle said.
Applejack knew the exact location.
"This way!" She made a turn to the left.
At last, they arrived at a barn. They nailed wood to block the windows and block the door with a cart.
"Did we lose them?" Rainbow asked.
"It seems like it." Spitfire answered.
"Why are we running from the people from CHS?" Scootaloo wondered.
"What happened to all of our friends?" Sweetie Belle asked.
"Rainbow, what's happening?" Soarin asked
Rainbow knew she couldn't lie.
"I think it's something in the cookies." She replied.
"Ugh! That's ridiculous!" Applejack chuckled. "Filly Guide cookies haven't changed for years! It's not like there's a new ingredient that's turnin' the whole town into cookie-cravin' zombies."
"Uh, unless there... is..."
"What are you saying?"
"What did you do?"
Suddenly, the arms of the swarming zombies reached through the window.
"Cover the windows!"
They hammered more wood onto the windows to block them from coming in.
"Okay! So I may have switched all the Filly Guide cookies for joke cookies that were supposed to make ponies' mouths rainbow but somehow turned everypony into mindless cookie-eating zombies instead!" Rainbow Dash told them.
"I told you actions always have a way of coming back to you." Spitfire told her.
"I get it! But I figure we just hide out here until the effects wear off, and as long as nobody else eats the cookies, we'll be fine."
"That's lovely, darling, except for one thing..." Rarity popped out of the dark shade to reveal she is already a cookie craving zombie! "We've already eaten theeeeeeeeeemmmmm..."
And Applejack too.
" Looks like your prank up and backfiiiirrrrreeeeed..."
Rainbow Dash screamed and dropped her light to show the CMC as zombies as well.
"Cooooooookiiiieeeees..."
Applejack kicked the cart out of the way of the door, letting every zombie in.
Rainbow Dash gasped.
"Get back!" Soarin demanded. "They could bite!"
The whole army of zombies got closer to them.
"No, no! Stay away! They're making you sick! You don't want these!" Rainbow Dash panicked.
"But we dooooooo... We want cookiiiiiiiieeeeeeees...!
Suddenly, as the moon shined through the barn, the Wonderbolts started feeling a little change in them. Their eyes glowed different colors, their teeth grew sharp, their voice sounded grouchy.
" Please! Stop! I never meant for this to happen!" Rainbow Dash shouted. "It was just a harmless prank! It was supposed to be funny! But this isn't funny at all!"
Then she heard growling behind her, she turned around and saw something different about the Wonderbolts.
They turned around in a different form....a werewolf form!
Rainbow gasped at the new form of them, they leaped right past her and landed in front of the zombie army. Together, they let out a loud and wild roar that echoed the whole barn.
With silence for a few seconds, the zombies were actually terrified. They all screamed and ran out of the barn.
They whole team were confused. Why did they run away? and why were they scared?
"That was odd." Spitfire said.
"I didn't know zombies can get scared." Misty Fly replied.
They turned to Rainbow Dash who was scared of their looks.
"Stay away, I'm don't taste good! I'm a dinner selection." She whimpered.
"Hey Rainbow, it's okay. We're not going to eat you." Soarin told her.
"You're not?"
"No. We maybe werewolves, but still have our correct minds." Spitfire said to her.
"I don't believe it, first I've everyone as zombies and now I'm seeing you guys as werewolves! Okay, things aren't adding up, what's going on here?
"We'll explain it at the academy."
At the Wonderbolt academy, Soarin explained to Dash that he was bitten by an alpha werewolf, giving him the ability of a werewolf. When the other Wonderbolts learned about this identity, they decided to team up with him and the became a team of werewolves.
"No way, that is awesome!" Rainbow Dash squealed. "But what that werewolf that bit you like before."
"I don't know." Soarin said. "But what I do know is that as long as we keep our identities a secret, no one will hunt us down."
"And despite that, how are we supposed to deal with a new zombie apocalypse in Canterlot?" Spirfire wondered.
"This whole thing is my fault. I used joke cookie filled with rainbow goo to prank everyone, but instead it turned everyone into cookie craving zombies instead."
"Don't worry, Dash. We'll figure out a way to cure everyone somehow."
Spitfire had an idea in her head.
"What if fear is the cure." She pointed out. "What if we scare everyone from zombies back to normal?"
The team was confused.
"How do you guys explain why they ran away?"
"Good point." Misty Fly said.
"If we're gonna save everyone tonight...then bite me!" Rainbow rolled up her sleeve and show her arm.
"What?"
"I started all of this, and I need to end it. If you guys are going to go wolf, then I must go wolf as well."
"I don't know."
"Please, this whole mess is my responsibility and I need to fix it."
"Okay, but I'm still uncomfortable about this."
Soarin took Rainbow's arm and bit her. Rainbow felt like she was about to feel transform. But nothing happened.
"Nothing's happening!" She exclaimed.
"It should work." Soarin said. "Maybe if you take a look at the moon it can help."
Rainbow Dash looked at the moon. The bright light shined in her face. But then she felt something inside of her. It looked like her werewolf transformation is about to happen.
"Oh yes! I feel it, I can feel it the wolf! I CAN FEEL IT! I CAN FEEL IT!"
Her eyes began to glow red, her eye began to sharpen, and nails began to grow sharp.
She was about to join the rest of the werewolf team to cure everyone with a little hunt. And maybe...just maybe...she could be the true alpha!
