Dear Princess Celestia... by Pinkuh Air Date: 21st April, 2018 Synopsis: The Cutie Mark Crusaders try to help a young hippogriff with family members on Mount Aris and seapony relatives in Seaquestria figure out where he belongs. Spoiler I'm pretty hyped for this one. I've seen a couple screen caps from this episode on the MLP wiki, and it looks like this might be a Twilight and CMC episode. Also, seaponies! Please remember to use spoiler tags as appropriate under 24 hours after this episode has aired on Discovery Family.
