I can't believe this group doesn't already exist! Perhaps it does, and my Google-fu is not strong, but for now...welcome to the group dedicated to the Best Changeling, Bon Bon!
The one common thing to all entries in this group is that Bon Bon is a changeling, whether she's ALWAYS been one and the reveal happens partway through, or she becomes one for Reasons™, Bon Bon is Best Changeling!
(Yes, even better than Chrysalis)
Submissions are open to anyone, moderation will be...light. (My last attempt to create a heavily moderated group...didn't work so well) Just make sure you stick to the main topic of Bon Bon being a changeling.
Wait, this is a Group now? *Joins*
