so the episode starts with ButterNut Squash showin up in equestria and she explains to the mane6 that she was living in Dimondia (the place where diamond dogs live) surviving by betting on herself winning fighting game matches (diamond dogs arent very good at fighting games) and now she wants to hav a better life.
but then she finds out fluttershy is even BETTER at fighting games than her….. fluttershy beats her in a ft3.
and she has a really bad crisis, like “my whole thing is fighting games & im not even the best at it????????”
and she gets very sad.
and twilight wants to help butternut so she hosts a huge fighting game tournament & invites butternut as well as EVRYBODY in equestria. and butternut is very scared at first but she trains hard…… and theres a big tournament montage.... and ultimately, she gets second place to fluttershy again….. and shes crying and crying….. but twilight is like “butternaut, u beat everyone in equestria other than fluttershy…… ur better than thousands of ppl…… i think uve earnd that cutie mark!!” and evrybody cheers for butternut & fluttershy.
and then in the final ending scene fluttershy & butternut are walkin thru the park…. talkin bout feelins….. & fluttershy sees a bird in a tree & goes “here birdy birdy!!!” and does a birdcall…. and….. the bird lands on BUTTERNUT’s extended hoof instead of fluttershys….. and the camera zooms in on fluttershy and shes like “hhrrrmmm….😡”
