[Stockapotapoulos]

I don't think its been mentioned, and excuse me if it has, but there's a chocobo named Boco fighting on its own against the boss in the following screenshot:

It carries the title Delita's Steed, and there's also a player named Delita on the roster (they both have their independant HP bars in the roster).

Also there's an AF dragoon with kain's name too.

You can see it more clearly in the PDF.

The chocobo mostly is whats driving me nuts with curiosity.

Hey, Wasn't Boko a fighting Chocobo in Final Fantasy V?
