The Secret of Tailsko

Chapter 1: Where's Tails?

Written by: KingSnow5092

"Tails! Where are you little bro?" Called out a male blue hedgehog with green eyes, spiky hair down his back, peach muzzle/inner-fur, peach arms, gloves, and red shoes, his name was Sonic. Sonic was wandering around in the forest looking for his fox friend, Tails. He had no idea where he was, he searched high and low for him but still can't find him anywhere. It was winter time on Mobius and there was snowing falling everywhere and it was very cold, the sky turned scarlet red because the sun was going down. Sonic walked out from the forest while holding a red scarf around his neck, the scarf was made by Amy Rose, another friend of Sonic.

"Where could Tails be?" Sonic asked to himself.

"SONIC!" Called out a female voice.

Sonic turned to find another hedgehog, it was Amy Rose the one who made him the scarf. Amy was a female pink hedgehog with green eyes, short hair, a red headband on top, a red dress, peach muzzle/inner-fur, gloves, and red shoes. She was wearing a blue scarf (guess why?). She looked at Sonic with an concern look on her face. "What's wrong Sonic?" Amy asked. Sonic frowned. "I can't find Tails anywhere, have you seen him Amy?" Sonic asked.

The female hedgehog shook her head and asked. "No, I haven't when was the last time you saw him?"

Sonic put a finger on his chin and explained. "Well, I recall the time I last saw him was when I saved him from Dr. Robuttink! He kidnapped Tails so he can tell him where the Chaos Emeralds were and he threatened Tails that he'll tell Sonic, that's me, his secret. But luckily, I came in and defeated Robuttink before he can do anymore damage. Afterward, Tails kissed me I was surprised when he did, so I asked him why he kissed me, when I did his face turned red and he ran off without saying another word and I never saw him again."

"Well, I'm sure he hadn't gotten far. He must be hiding around here somewhere." Amy assured Sonic while putting her hand on his shoulder. "Thanks Amy." Sonic said, putting his hand on Amy's hand. The two hedgehogs smiled then Sonic snapped his fingers. "Wait a minute! I know where Tails might be! He might be back at his lab working on a new experiment of some kind!" Sonic exclaimed.

Amy nodded. "Of course! That Tails loves to invent things!"

"Yeah! That's where he's hiding! I'll go get him and ask him why he's been hiding this whole time." Sonic said. Then he sped off to Tails' workshop. "OK Sonic! Tell Tails that I said hi for me!" Amy called out. "OK!" Sonic called back. Then Amy frowned thinking about Tails. "Poor Tails, he must be cold in that workshop all by himself." Then he smiled and said. "I'll go make him a scarf too!" Then she skipped away to her home to make Tails a scarf.

Meanwhile, Sonic skidded to the halt next to Tails' workshop. Sonic walked up and knocked on the door. There was no answer. Sonic knocked on it again. But there was still no answer. Sonic sighed in frustration. Then the blue hedgehog decided to just go in, Tails didn't mind Sonic going in without knocking on the door. So, Sonic opened the door and closed it behind him. Then he turned on the lights to find no one was there! Sonic looked around Tails' workshop to find some tools, papers, blueprints, paint cans, and other thing scattered around the floor. The workshop was abandoned! The hedgehog was surprised to see that Tails wasn't even home. Where could Tails be?

Then Sonic noticed something on one of Tails' workbenches. It was a piece of paper. Sonic walked up to the workbench and grabbed the paper. He found the paper was a note for him. So Sonic began to read it said.

Dear Sonic,

By the time you're reading this letter you'll know that I have gone back to my original home on Westside Island

to be a loner again! Don't bother coming to get me Sonic, because I'm not going back home ever again.

Don't worry though, I'm sure you'll find another smart friend like Wave the Swallow, she's as smart as I am.

I'm sorry Sonic, but it's better this way than to find out my secret. Good-bye.

Your Friend,

Tails the Fox

Sonic couldn't believe what Tails wrote about him not returning home and getting another smart friend. The hedgehog felt tears in his eyes after he had read the letter but he wasn't going to cry. He knew it was okay to cry there was no shame in that, but however Sonic was Mobius' #1 hero and he wanted to remain tough and strong like the other heroes in the cartoons. But then Sonic shook off the feeling and had a stern look on his face. "What am I doing? I can't just stand here and let my little buddy be a loner! NO! I'm going to Westside Island and get my buddy back!" Sonic said determined. Then he dropped the letter and ran to the area where Tails' blue airplane called Tornado was sitting in.

Sonic opened the double doors to find that the airplane was gone as well! Sonic slapped his forehead in anger and sighed. "Oh great! Now, how can I get to Tails without an airplane?" Sonic asked himself. Then Sonic snapped his fingers and said. "Of course! Duh! I'm the fastest blue hedgehog around, I'll just run to Westside Island and get Tails back!" Then Sonic ran outside from the airplane dock and ran over the waters to Westside Island, which was now ice.

Sonic had arrived on the beach of Westside Island in ten seconds flat. Sonic looked around the island to find that it was covered with snow like back at his home, he looked around until he found Tails' airplane. Sonic gasped at the sight of the plane. The hedgehog ran up to the blue plane to find it covered with snow. The Tornado was blue with Sonic's name on it. The plane had two seats for each passenger/pilot, wings, and standers on top. Now it was covered with snow with some icicles dangling on the bottom of the standers, snow was piled up in the seat, and Sonic's name was almost faded. Sonic got the closer look at the plane as he rubbed his fingers across his name. He wondered why Tails left the plane out at the beach?

Then he saw a yellow light in a distance, it was coming from an orange house. The house looked ordinary but there was something familiar about it. Sonic decides to get a closer look at the house. Sonic sped across the jungle and stopping in front of the orange house. Sonic got a better look of the house now, the house was huge painted orange like Tails, the roof was covered with snow, there were five windows on the house, a spotlight on top of the house to keep out enemies, and a big lock in front of the house to keep out intruders. Sonic was confused now. He knew Tails was a genius but this was taking things too far.

Then Sonic noticed that the house had a backyard too. Sonic sped around the backyard to find the back of the house similar to the front only difference is there was a ladder next to the bedroom window. The backyard was clean and clear, with some jungle brushes surrounding it, an enterance to another part of the jungle. Sonic looked up to the bedroom window to see the lights were still on. Sonic wondered if this is where Tails might be. So the hedgehog grabbed the ladder and sped up to the window, opened it and slipped inside. He tumbled over as he did, but he got up dusted himself off and closed the window in case anyone else tries to break in.

Sonic looked around the bedroom to find two doors, one leading outside of the bedroom, another leading to the bathroom, an orange-colored Tails-size bed that Tails sleeps in, a nightstand with drawers, an alarm clock, a picture of Sonic and Tails, a lamp that give off light, the walls were yellow, and the rug was blue, the dresser which contains Tails' belongings, and on top of it, a toolbox, and a desk with a computer on it next to the dresser. Sonic liked Tails' room. Then he heard someone opening the bathroom door, he turned to find that it was his bestfriend, Tails.

Tails was a male orange fox with blue eyes, three bangs over his head, white muzzle/inner-fur, gloves, two soft, fluffy tails, and red shoes. He was drying himself off with a towel, it was obivous that he took a shower after the long day. He threw his towel in a hamper of the bathroom to dry. As he left the bathroom, he gasped in surprise to find Sonic standing there. "Hi Sonic." Tails said. "What are you doing here?"

Sonic smiled. "Hiya! Tails! What are you doing back at your original home on Westside Island. Why don't you want to come back?"

"Well, Sonic you see there's something I need to tell you." Tails said, looking down.

Sonic frowned. "Sure Tails, what is it little bro?"

Tails gestured Sonic to sit down on his bed which Sonic did. Then Tails continued to talk. "Well, Sonic, you know when you saved me from Dr. Robuttink I thanked you by kissing you?" Sonic nodded. "Yeah, I was wondering why you did that."

"Well, Sonic to tell you the truth there was a reason I kissed you." Tails explained.

Sonic rasied a eyebrow and said. "I knew there was a reason because I told Amy that, who is soon to be my girlfriend, and she thought it was weird too." Tails' eyes widened after Sonic said that Amy was going to be Sonic's girlfriend. Tails growled a bit and he was angry at himself for not telling Sonic the truth sooner. Well, now he was going to tell Sonic the truth now or never.

"AH! I CAN'T TAKE IT ANYMORE!" Tails shouted.

"Tails? What's wrong?" Sonic asked.

"SONIC! I'M A GIRL!" Tails blurted out.
