You're going to need a bit of background before you dive into this uniquely disturbing video by uniquely disturbing YouTube gore-meisters RackaRacka. It's a parody and kind of mashup of survival horror video game series Five Nights at Freddy's by Scott Cawthon.
The series centres around a pizza restaurant where you play a security guard who has to battle the creepy animal animatronic night terrors that plague the restaurant.
RackaRacka have merged that concept with the cuddly loveable characters from perennial children's favorite Sesame Street, as they along with the teddy, Freddy Fazbear, from the game series turn into some kind of demons and come to wreak violent horror on some suburban kids.
It's played out like it's a trailer for an upcoming horror film, and there's just too many weird and freaky things that happen in it to list.
Plus, to mention them would be to ruin the surprises. Just watch it—and brace yourself.
As one freaked-out YouTuber commented, "Im going to bleach to bleach my eyes after the baby bird scene. i was messed up."
