t seems coco had a little help from an unknown pony in order to make a new line of clothing involving jester hat thingies , however it seems this certain pony has made some "changes" to the planned desing, and afther coco put it on to model it, it melted her mind and turned her into a mindless hypno jester , who will entertain every pony that crosses her path with her hypno tricks and make hypnotized assistants

someone write a store for this in fimfiction but i do not remember the name nor have the link if you find it leave it in the comments
