It appears Twilight Dapple and Eventide Glisten were wanting to practice their transformation spells, and figured Pterus was the best pony to practice on. But they only learned part of the spell, and by adorable accident, their big brother is now their little baby brother, but they have not yet mastered how to reverse this particular transformation. And this isn't the first time they've involved their brother in magic practice. Mother Twilight Sparkle is none too happy that they used another spell on their brother, and Twilight Dapple is arguing that she wants Pterus to stay an adorable foal. Mommy Luna doesn't seem to mind that her baby boy is now her actual baby boy. Pterus? All he's doing is wondering why Mama Twi is yelling at his sisters…….. and when did his sisters get so big and his Mamas become titans?

What shenanigans will happen next?
