I’m still not really sure if Pinkie’s trip to Yakyakistan happened at all; she’s kinda unreliable when it comes to narrating events. Or maybe it did happen, but it happened on another day, during some completely other unrelated adventure, and she’s just mixing up the days. Or maybe it happened in a parallel universe and due to her reality-bending tricks, it’s leaking into this universe. Who knows?
Is Pinke living on the top or bottom floor? Her bed moves all around.
When she’s looking out, is from the top window. When she listened to Twilight-Cake conversation (S1E25) it was from the top floor.
But this scene, amongst other - they enters the front door directly into her bedroom.
