Pinkie Pie, Starlight Glimmer, Scarlet Witch (Wanda. But also the red pony with reddish brown hair), and Bat Girl (Cassandra. But a grey pony with a black uniform). The foal Enchantress, Amora, has a plan to get her revenge, so it's only natural that when the adult ponies arrived at the daycare in Ponyville, Amora regresses the four adults into foals as well, three of them crying because of what happened, whereas Pinkie Pie is just laying there in a good mood. Sadly for Wanda and Cass, their clothes stayed the same size and because they were too big on them once regressed, the clothes fall off, although Wanda's tiara barely fits her at all and it's the size of her head.
