I remember making a episode 3 FAN-FIC a while ago for episode 3, lemmme dig it up.
OK, so it is about Twilight sparkle messing up on a spell, tuning pinkie pie into a unicorn. Pinkie then starts to take over ponyville by hypnotising everypony with her horn that gummy is their ruler, parties are everyday things and that candy is for dinner lunch and breakfast. Ponyville goes currupt as pinkie uses her wings to make everyday sunny with rainbows. Everything dries out and ponies go colorblind. TS tries to stop her before she turns all of equesteria into a pink cupcake.
