okay now hear me out but changelings could have worked in G%
>have their hive be discovered in a far removed region or (more than likely) a cave below the town
>given their separation and the passage of time they reverted to their original form
>their arc could be about self acceptance and learning to love who and what they are or some shit
>they also already know how to share love they just choose to look evil and scary because theyre isolationist or something with the only bug choosing to look rainbow being the first bug the mane cast encounter and befriend
>they could then be neatly intigrated into the background maybe knowing transmutation magic to do arts and crafts or pottery with the gang
>it is also a given that their designs would be botched to shit just like the dragons but that should go without saying
