Changeling Space Program (Features changelings)
Aunt Millie (Based on the scene in Flutter Brutter)
Being Juniper Montage (Should be obvious)
The Cutie Mark Crusaders Get Feather Banged (Should be obvious)
The Strange Case of Dinky Hooves’ Cutie Mark Curiosity (Explicitly has the CMC with their canon cutie marks)
This Game of Mine (Secondary Main character is Button Mash)
These I’m not sure:
Time to Die
Through the Well of Pirene
Apogee Gets Dizzy
Apogee’s Head is in the Clouds
The War of Ours
Starlight Starbright (Could be Starlight)
The Maretian
Three More Things!
Did I miss any?
