I badly need help one of of my one-shot stories I'm about to make. I'm posting this here because I have no ideas! Could you help?

It needs to be something about Apple Bloom, Sweetie Belle, Scootaloo, Diamond Tiara, Silver Spoon, and Babs Seed. (I always liked Babs on DT and SS's side)

4544185 Poison joke makes Diamond Tiara and Silver Spoon lose their cutie marks. When they run out of ideas, they knock on CMC's clubhouse. They have some apologizing to do first, though.

4544538 Hm...nice idea, I'll think about it.
