It was apparently found by accident in a toy snop in Mexico because they were sent the wrong toys. If Activision still haven't found out about Flyer Kraken (which they probably have because Acti have reps on this forum, but there's still a chance) being sent to the shop in Mexico, they might accidentally send more prototypes, thinking there're still sending it to the right place. Even if they did know about Flyer Kraken, they might not know about the toy shop, or might of already sent the next prototypes. I don't know much about how shipping works, though.
"Alright Joe, did you pack up and ship those Flip Wrecks yet?"
"Yeah, was that gray guy with the engine on the base and some weird flame wings? I shipped every single one of them!"
"JOE...? JOOOOOOOOE! ...You're fired."
I wonder what Activision will actusally do now that there are prototypes at this toy shop. I would think they would just either take pictures or videos down since it's just one shop, or they'll do nothing like they did with the mega bloks leak, hoping that we think it's fake.
