For the record, Dragon Clap and Troll Crabs come from cloneserpents' "Crack'd Mirror" story. Personally, given Ginny's behavior, as shown in that flashback, I'd love to see her get both as well as see Ron get one or both as they've both earned such a "reward".
As an addendum to my above comments, I'd like to say that I've got nothing but sympathy for Hermione, but at least she's intelligent enough to take precautions (I most certainly hope she did) so she doesn't/won't have any other reminders of her "crazy time" with Ron.

- Ah, yes. Cloneserpents is a genius.
- No STD will be part of this story (no matter how funny it might be.)
