DoubleTale: A Random Story of two OCs in Undertale

First of all, this is just a random idea I had and also my first fanfic, so don't expect much. Feedback is appreciated! This may get multi chapters, I don't know. I (the writer) am Elsa and Misha is a friend of mine. There will be no shipping.
(Misha's fingerless gloves were his idea, not mine in case anyone thought we copied the idea off of each other).
Italics is Shadow speaking/thinking, bold is Blaster speaking/thinking, Bold/Italicsis them speaking at the same time, and normal is everyone else.
Finally, Shadow belongs to me, Blaster belongs to Misha, and everyone/everything else belongs to Toby Fox, creator of Undertale.

Elsa woke up on a bed of golden flowers. Misha was lying next to her. She could see sunlight filtering through the foliage above her. Where were they? And how where they here? She didn't remember falling down a hole.
She looked around. Rock walls, water dripping from the ceiling. Nothing of much interest. Apart from a small corridor leading off of the room. It all seemed strangely familiar... Until it hit her. They were in a video game she had been playing a lot recently. Undertale.

Elsa shook Misha awake. Suddenly a fireball appeared out of nowhere, and headed straight for her. Elsa flinched at the searing heat. When she opened her eyes (a split second later), she was on the other side of the room. "What the f*** just happened?" she said, just as Misha said the same thing. "Jinx!" they both said at the same time again. They both laughed.
"Misha, I think we're in Undertale." said Elsa suddenly, in her usual way of saying things entirely unrelated to the current subject or mood.
"What?!" replied Misha.
"We are in Undertale as our OCs." continued Elsa.
"WHAT?!" near-shouted a shocked Misha.
"Remember that game I showed you loads? Undertale? The one with the b**** flower and the funny skeleton that loved spaghetti and the punny one that was also a badass in the genocide run?" Yeah, that game." Elsa told Misha.
"OK, this is getting weird. We are in a VIDEO GAME?! Please tell me this is just a crazy prank..."
"Nope. Just crazy, logic-less, likely fanfic-driven bulls***."
"S***."
"Anyway, we need to work out what to do. I've a feeling we need to get an ending to get out of here, so we need to decide which route to take. I suggest pacifist."
"Genocide might be fun."
"Misha what is wrong with you. I admit it might be interesting but WHAT THE F***!"
"Fine. Coin flip."
"*sigh* Fine."

A coin appeared out of thin air into Elsa's hand. 'Well that's new. Might be a fun trick to use.' Elsa thought. 'Heads for pacifist, tails for genocide?' asked Misha.
"Sure." replied Elsa.
Misha threw the coin into the air. It flipped over and over, glinting in the patchy sunlight, before landing, head side up, on the ground.
"Yaaaaaas! Pacifist run!" I didn't want to kill Toriel anyway!" said Elsa happily.
"Who's Toriel?" asked Misha.
"Goat mom. She saves you from Flowey." replied Elsa.
"Speaking of which, I should probably tell you how the battle system works, for when we meet Flowey in a little bit. You see the little heart on your hand?" said Elsa, gesturing to the green heart on the back of the fingerless glove on her left hand.
Misha glanced at his left hand, and saw the orange heart on the back of the fingerless glove on his left hand. "Yes." he replied.
"Good. Enemies attack by firing white things at you, which reduce your HP if they hit your SOUL aka your little coloured heart. There are different colours of attack, but those don't appear for a while yet. In battle mode, there is a small box which contains your little heart. You move it around inside the box to dodge attacks. Outside the box, there are four options. Fight, which is off-limits till the Asgore fight. Act, which we'll be using a lot to persuade enemies not to fight. Item, which lets you use items, which you use to restore your HP, and Mercy, which you use to either run away from a fight or spare enemies. Got that?" asked Elsa.
"I think so." replied Misha.
"Also Misha, since we're in a video game, we might as well use our YouTube names. You know, because they're our OC names and we're our OCs. My name would be ShadowCat 500 and yours would be Blaster 007. We should remove the numbers though. It would be kinda weird to call each other Blaster double-0-seven and ShadowCat five-hundred, right?" said Elsa.
"You're right. I'll call you Shadow and you call me Blaster, OK?" said Blaster.
"Sure." said Shadow. "Also, we should follow the script as closely as possible, and not do stuff like attack out of turn and just immediately destroy Flowey. We don't know how badly we might mess up the timeline."
"OK then. Onward to victory!" shouted Blaster, doing a knight-like pose, holding an imaginary sword, as Shadow laughed.

"OK, for the Flowey fight, I'm sorry but we both have to stay inside the circle of pellets and not move. Remember to dodge the first attack, ok?"
"OK."
They both entered the room Flowey would be in. As expected, Flowey was in the centre of the room. 'Howdy! I'm Flowey! Flowey the Flower!' the golden flower said brightly.
'Well thank you Captain Obvious!' Shadow whispered to Blaster, getting a small snigger from him in return.
'Hmmm... You two are new to the Underground, aren't ya?' the flower continued regardless. 'Golly, you must be so confused. Someone ought to teach you how things work around here! I guess little old me will have to do.'
'LOL we've already been through this!' Shadow whispered to Blaster, again getting a small snigger.
'Ready? Here we go!'
The battle screen appeared, with a green heart and an orange heart inside the box in the centre.
'See those hearts? Those are your SOULs, the very culmination of your being! Your SOUL starts out weak, but can grow strong if you gain a lot of LV.'
'Level of Violence. Ask what he means, anyway.' whispered Shadow to Blaster.
'What does LV stand for?' asked Blaster.
'What's LV stand for? Why, LOVE of course!'
'Told you he was a lying piece of s***.' whispered Shadow again.
'You want some LOVE, don't you? Don't worry, I'll share some with you! Down here, LOVE is shared through... Little white... "friendliness pellets." Are you ready? Move around! Get as many as you can!' said the little golden flower as he fired a small swarm of little white pellets at the two hearts. The two hearts neatly dodged all the pellets without getting hit once.

Yes I know I should have ended t with meeting Toriel but I couldn't find out Flowey's dialogue if you dodge the pellets on your first run. If anyone can tell me what it is in the reviews or by PMing me it would be much appreciated. :) Bye!
