Although I do think it would be interesting if a Scootaloo issue focused on her inability to fly.
I don't really get why she can't fly. Is it only her? Pound Cake would fly and he's a baby.
My personal guess with that is that it's
because Pound Cake's a baby. Scoots is a lot bigger than Pound Cake, but their wings are still about the same size. Thus, it's harder to move Scoots around than Pound Cake.
Alternately, it's another
wild magic thing. Pumpkin Cake was using magic instinctually, but when was the last time you saw Sweetie Belle do any magic?
