Mordecai and Rigby at Freddy's is a fanon crossover special of Regular Show and Five Nights Freedy's, which is about how Mordecai and Rigby got their new job at Freddy Fazbear Pizza as night security guards, after quitting The Park. But the animatroics literally comes alive and hunts the duo down during the night.
(The episode opens where Mordecai and Rigby are sitting on the sofa, feeling bored)
Rigby: Uuuuuuhg! Boooooorrrrrriiiiinnnnnng! Boring, boring, boring!
Mordecai: You're telling me, dude.
Mordecai: Yeah, boring. There's nothing to do around here at all.
Mordecai: Yeah, just sitting here staring at the TV.
Mordecai: Yup. Bored and nothing's fun going on in The Park. Nothing at all.
Mordecai: Okay, dude, really, please stop that.
Mordecai: I mean it! You're already said "boring", like couple times.
Mordecai: Rigby, dude, stop.
Mordecai: (angrily) Stop!
Mordecai: (annoyed) Dude, shut up!
Mordecai: Ugh! Seriously, dude? I mean, are you going to say that same word often, all day?! It's now getting annoying!
Rigby: Bor--- (irritated Mordecai punches Rigby to his arm) OW! HEY! That's uncalled for, man!
Mordecai: I guess that'll shut you up alright, huh?
Rigby: OK, OK. I'm done now. I'll stop saying "bo--". (seeing Mordecai raises his arm trying to punch again) I mean the same "B" word, if you wish.
Mordecai: (drops his arm down) Finally, thank you.
Rigby: Whatever. How about we'll play video games. Are you mood for that.
Mordecai: Sure, why not?
(Clock transition to few moments later where M&R are playing their old video game and got bored again)
Mordecai: *Sigh*, I don't think I'm mood for playing this. (turns off the video game system)
Rigby: Me neither, this is also.... "B" word. Playing the same old-fashion video games in our old-fashion gaming hardware. I mean could get a new-fashion video game system and as well as new-fashion games. Like why we always playing the same 80s video games in this 80s system? We're not in the 1980s, we're in the 21st century, for crying out loud! Plus this house should need some new-fashion stuff as well, I mean, look around everything's old! This house is been like what? Long time ago since The Park's founding?
