EDIT: Just found this story about Rafael (the site's one of the companies involved with the Filly brand), translation requested: http://www.blue-ocean-ag.de/node/341/view

Like me and Zimsala? Maybe we're repressing information so that we've got "new" stuff to find!
>>"First appearance" box added to Character infoboxes: I figure it can be used for both toy characters and show-only characters (for whom it will be their first episode).

It does help with those stray Filly sets, but currently backfiring for the exclusive Fillies. I THINK Varita first appeared in the Filly Unicorn metalbox/tinbox series 1 (the one with Loki and Ashia on), but that's mostly because I can't find her gold-crowned figure associated with anything else. It's possible the tin itself was an exclusive. Similar case for Fortuna, though, judging from the "series 5" thing that comes up, sellers still consider the first few series (e.g. Forest) to be of note, ha.
<On the bright side, I IDed the pink house of Flora's: It's the Dream House from the playset she was released with.
