The cutie mark crusaders cutie marks are probably: -Sweetie Belle is singing -Scootaloo is dancing -Applebloom is painting または renovating I got all of these 回答 from other fans, so I don't kow if they're correct または not...
I'm kind of hoping they someday bring out some brushables of the fillies after they have earned their cutie marks! Maybe something for them to do after FiM has finished (or if they do earn their cutie marks in an episode).
My guesses for them so far: 林檎, アップル Bloom - a red 林檎, アップル inside a ピンク flower. Sweetie Belle - a microphone with stars around it. Scootaloo - a scooter with speed streak lines behind it.
My "headcanons" for how each one earns her mark: 林檎, アップル Bloom - she is designing (or maybe fixing) the inside of a barn, combining her design/decorating skills with working on her family's farm. Sweetie Belle - something happens that causes her to forcefully overcome her fear of 歌う in front of a large audience. Scootaloo - she performs a seemingly impossible 移動する on her scooter that no other ポニー has ever done before, a little like 虹 Dash with her sonic rainboom.
