Based on SMG4's Mario/FNAF crossover sequel. (Once again, without bad words and inappropriate scenes; alternative scenes with Frozen)
Elsa, after she worked at the scary pizzeria, she spent the gold to get some new electronics she has discovered when she was working at Freddy Fazbear's, and it includes a TV, an iPad and a computer. After she bought this, Anna, Elsa, Kristoff and Olaf had to learn how to use the computer, iPad and TV, and they did after several tries. Two months later, when she was watching the TV she had bought, she finds out there was a new commercial for Freddy Fazbear's.
At the sight and sound, she leans in to listen to what's going on with Freddy Fazbear.
As it turns out, it wasn't a restaurant commercial. It was something like a trending horror game like Slender. It was called "Freddy's Pizzeria" for PC, which stands for personal computer. The commercial says:
Super spooky and fun gameplay!
Friendly characters and happy gameplay!
Buy it now!
"Very scary. Again.", Elsa says in a suspicious way. She walks away and starts to yell "I CAN'T BELIEVE THAT STUPID PIZZERIA (that sells chocolate too) MADE THEIR OWN GAME! THEY MIGHT'VE FIRED ME AND THEN THEY MADE THEIR GAME?! WELL, HA! NO ONE IS GONNA PLAY THAT GAME!"
She clears her throat, thinking that Anna might hear her, but she is at the fjords, romantically fishing with Kristoff.
Suddenly, Elsa hears someone scream upstairs, and she hurried up the stairs to see what has happened.
When she opened the door to the room with the computer, Elsa finds out that Olaf has bought Freddy's Pizzeria and is playing the game right now.
"Olaf! What are you screaming about?!"
"...I'm not playing Freddy's Pizzeria."
"Olaf..."
"But it's spooky and happy!"
"And it's not for you.", Elsa says in a sweet way.
"And it's not for me.", Olaf says. "Can I just play it one more time, please?"
"Sorry, Olaf. That's enough for today.", Elsa apologized as she tried to turn off the computer, but fails when Olaf lunged at her. "OLAF!"
"I wanna play one more!", Olaf yells.
"I bet that game isn't that good!", Elsa argues.
"Try me! You try to beat it, you win. You refuse to beat it, i win.", Olaf waged.
"No dares?"
"No dares."
"Ok. I could play this game with my eyes closed.", Elsa bets.
As she plays the game, she is immediately startled, who then falls backwards, still, and her ice slippers fall off as she fell.
The game says:
GAME OVER, YEAAAAAAH!
WOULD YOU LIKE TO PLAY AGAIN?
Elsa's POV: She opens her eyes to see Olaf looking down at her saying: "Elsa! Are you ok?"
Exit POV: Elsa says, shaking her head to get consciousness, "Boy. That was scarier at the time I was at Freddy Fazbear's."
She then starts to sing Let It Go again, but Olaf blocks the door as she goes out the door.
"Nuh-uh! You can't leave! Unless you lose the bet!", Olaf waged again.
Elsa growled louder and louder until she yells again, "YOU KNOW WHAT?! I'M SO GOOD I CAN TRANSPORT MYSELF INTO THE GAME AND BEAT THOSE ROBOTIC ANIMATRONICS...AGAIN! I'M READY TO GO THERE AGAIN, NO MATTER WHAT!"
Just then, a spark of troll magic has struck the computer and unleashes a portal which begins to transport Elsa and Olaf into Freddy Fazbear's Pizza by sucking them. Elsa was sucked into the portal, but Olaf blocks the portal with his head.
Elsa arrives at the pizzeria, and yells to Olaf "OLAF! GO BACK! I WAS JOKING! I DON'T WANT TO BE HERE!"
"It's not your fault or mine! I can't go back! My head's stuck!", Olaf yelled back.
"Tell me you're kidding!"
"No, I'm not!"
Elsa's heart sank as she finds out she is at Freddy's Pizzeria again.
Looking around, she discovers that the pizzeria doesn't look the same as she was before, and she noticed the same computer, phone and security system.
"Don't leave me all alone!", she screamed to herself.
Elsa was startled by the voice once again, and she knew it was the phone. The message says:
"Welcome to your new summer job, Freddy Fazbear's Pizza."
"NOOOOOOOOO!", she yells to the ceiling, knowing she thinks she has to restart at a newly-renovated Freddy Fazbear's Pizza.
