This is a request from Autumn. I'll make Sonic 11 and Tails 4.
Disclaimer: I don't own Sonic the hedgehog and never will.
Sonic and Tails were running toward Sonic's favorite flower field. It was a peaceful place where the flowers were so bright when the sun was out. They always came here once a week to relax by admiring the flowers and taking a nap.
When Sonic and Tails arrived at the flower field, they went up to the only tree and sat down with their backs against the tree. The both of them yawned and put their hands behind their heads closing their eyes falling asleep.
After 5 minutes of sleeping a rustling sound was heard causing Tails to open his eyes since his hearing is stronger than Sonic's. He heard the rustling sound again and he stood up looking around trying to pinpoint where the sound was coming from. His gaze fell upon a shrub as he saw it move a bit.
Curious Tails slowly walked over to the shrub in case it was an Eggman robot spying on Sonic. When Tails reached the bush, he carefully pulled back the bush and was surprised at what he saw.
A small yellow chao was staring right at him with a confused look on it's face. The chao blinked and tilted it's head as the ball above it turned to a question mark.
Tails smiled and picked the chao up hugging it making the ball turn to a heart. "Hey little guy, what are you doing out here by yourself?"
"Chao chao chao chao."
Tails frowned. "Um, sorry but I don't understand chao language." Tails then smiled again. "Hey, want to meet my adopted older brother?"
The chao smiled and clapped it's hands as if saying yes.
Tails than walked over to the tree where Sonic was. When Tails came to the tree he shook Sonic gently as not to make him think it was an Eggman robot. "Hey Sonic, wake up. You won't believe what I found."
Sonic slowly opened his eyes and yawned. "What is it Tails? I was napping."
Tails put the chao in front of Sonic's face so he could see it. "I found a chao."
Sonic who was now awake smiled. "That's great little bro. Where did you find him?"
Tails pointed to the shrub. "I found him over there. I heard a rustling sound and at first I thought it was an Eggman robot."
Sonic smiled and petted the chao making the emotion ball turn into a heart. "You like that don't you?" Sonic asked.
"Chao chao!" the chao exclaimed happily.
Sonic laughed. "I'm glad you do."
Tails looked at the chao to Sonic and smiled. "Hey Sonic, can I keep him?"
Sonic frowned. "I don't know Tails. What if he has an owner, but got lost?"
Tails looked at the chao. "Well do you have an owner little guy?"
The chao frowned and shook it's head. "Chao chao chao chao chao chao chao chao chao chao."
Sonic frowned. "I'm sorry to hear that. I can tell by looking at you that your a new born, is that right?"
The chao nodded it's head. "Chao chao."
Tails looked at Sonic with a shocked expression. "You can understand chao language?"
Sonic nodded his head. "Yep, I could always understand chao language."
Tails blinked. "Well what was he saying before when I asked if he had a owner?"
"He never had a owner before and was only hatched yesterday. His parents died unexpectedly yesterday as well." Sonic said.
Tails looked at the chao with a sad expression. "Is this true?"
The chao nodded it's head.
Tails cried and hugged the chao. "Oh Sonic, we have to keep him! He has nowhere to go!"
Sonic sighed. "I don't know Tails, your only four and taking care of a chao is a big responsibility. He could always go to the chao garden."
Tails frowned. "But Sonic, I promise to take good care of him! Please can we keep him?"
Sonic looked from Tails to the chao and sighed. "Very well. If you can handle him than he can stay with us."
Tails grinned and looked at the chao. "Did you hear that?! Your coming with us!"
The chao's emotion became a heart as it clapped it's hands happily.
"So Tails, what are you going to name him?" Sonic asked.
Tails rubbed his chin. "Hmm, I think I'll name him Sparks!"
Sonic laughed. "Well Sparks it is then! Now how about we go back to napping?"
Sparks yawned and rubbed his eyes as if agreeing with Sonic.
Tails smiled. "Okay Sonic." he said as he and Sonic walked back to the tree and sat down.
Sparks flew up on Tails' head and fell asleep making Sonic and Tails smile.
Sonic and Tails looked at each other smiling before they fell asleep with their new family member.
