Sonic and Frisk looked ahead of the house and tree in front of them.
"So... Should we knock first?" Frisk asked as they went to the front door, lifting his hand ready to knock.
The blue hedgehog nodded, and the human did so.

But as Frisk knocked, the door opened by itself.
Inside was quiet, like someone was out shopping.
"Funny, I'm pretty sure if I was the owner of this house. I would lock it and..." Sonic said to himself looking at the door and the surroundings.

It had what a home needs, cupboards, a living room with a table and a few chairs. And a kitchen on the left, and a few more rooms on the left.
In the middle, some stairs that go down somewhere. That's when Sonic looked at Frisk who looked pale.

"Hey Frisk, are you alright?" The blue blur asked the child.
Frisk looked back to the hedgehog.
"There is something that doesn't feel right down there..." Frisk weakly said to Sonic.

Worried about the kid, Sonic went down.
"You stay here alright, I'll go down and look." He said to the child and climbed down the stairs.
"Okay."

As he climbed down the stairs, the hallway was dark and cold.
It made him real nervous, but he wanted to find out what's going on.
"INTRUDER...DETECTED!" Shouted out a robotic voice.

Determined, Sonic continued mocking forward and turned around the corner.
There he saw what made that voice.
A robot floating towards him.

It moved towards him, lifting on of it's hands.
Sonic looked at the design, noticing something familiar.
It was he logo of his enemy... Dr. Eggman.

"Did Eggman build you?" He asked the robot.
"DESTROY HEDGEHOG!" It shouted, shooting flames from it's right hand.
But the blue blur luckily dodged in time, as flames roared behind him. "Yup, made by Egghead..."

"help... me..." Somebody told Sonic inside his head.
Who was calling him? Just then, his Soul came out.
Sonic began to spin dashed towards the robot, as it was getting ready to attack again.

Sonic's Soul began to glow and rushed towards the robot.
The blue blur began to go inside the robot's Soul Container.
Not knowing where he's headed.

"What the... Where am I?" Sonic asked as he looked around him.
He was in a dark purplish place with green lines made to look like bricks from the ruins.
"Help me..." A voice called out to him again.

Sonic went towards to the voice's owner, while avoiding some flames that were trying to kill him.
"Don't worry! I'll try and help!" Sonic called out as he ran.
He knew that Eggman was in this place as well. (Not very subtle Eggman)

Sonic saw some things at the very end.
One was the Soul Container he saw, only bigger.
The one was what looked like a goat woman screaming in pain.

"HELP ME!" The goat woman shouted as she tried to destroy said container with flame magic.
Only the container absorbed her fire, and shot it towards the Blue hedgehog.
Luckily, he dodged in time and helped her.

Sonic's Soul lit up, and shot at the container.
"Are you alright?" He asked the goat woman as he lifted her up.
She nodded weekly, tearing up.

The goat woman looked at Sonic's Soul, glowing like at nightlight.
"Please, help me destroy that thing and get my Soul out please..." She told him as she readied her fire.
Sonic knew that if she did, it would asorb it, but probably together with his Soul, that would help out.

So the blue blur lifted up his left hand his Soul got brighter, shooting a beam of light, while the goat woman shot her flames at the same time.
Destroying the Soul Container, and freeing her Soul.

Sonic Woke up, and in place of the robot was the same goat woman, he looked back.
No more flames behind him.
"I would like to thank you." The goat woman thanked the blue headgehog as she walked towards him.

"Your welcome. I'm Sonic, Sonic the hedgehog." He said his name, waiting for the goat lady's response.
"My name is Toriel. The caretaker of these Ruins." Toriel told Sonic.
"Oh, got to head back and see if my friend is alright." Sonic said as he headed upstairs to see if Frisk was alright, Toriel followed.

There, he saw Frisk on a table chair, reading a book.
"Hey Frisk, your alright!" Sonic called towards the human.
Toriel looked at Frisk with a surprised look.
