This is how the gang meet Kristoff and Sven in Ryan F-Freeman's Adventures of Frozen.
[The gang heads to a stable where Kristoff is with Sven]
Kristoff: Reindeers are better then people~
Sven, don't you think that's true?~
Kristoff (as Sven): Yeah, people will beat you and curse you and cheat you~
Every one of them's bad except you~
Kristoff: [pets Sven] Oh, thanks, buddy. [sings] But, people smell better then reindeers~
Sven, don't you think I'm right?~
Kristoff (as Sven): That's once again true~
For all except you~
Kristoff: You got me. Let's call it a night~
Kristoff (as Sven): Goodnight~
Kristoff: Don't Let the frostbite bite~
[Ryan and Cody clap thier hands]
