is it noramal for him to come with two cyber keys? i got one today misb opened it and as well as the one on display he had one in his tail mount.
Are they both the same Jungle Planet kind, with the proper code? Normal, that most certainly isn't. You 100% sure he was MISB? Sounds like a mistake someone would make while reselling or returning a figure, like the guy at Botcon who ended up giving someone two Nightbeats with A. Sideswipe because he didn't notice one of them in the car.
I broke the seal myself, both have the same code and he wasn't bought second hand. It must have been put in at the factory to see if the gimmick worked and then not removed.
Maybe one of the factory workers got carried away with enjoying him. Although I don't go to these Chinese factories to know for sure, I'd guess they only test the Key gimmicks for one out of every X figures, and perhaps that included yours, only the key didn't get removed like it probably should have. Eh, it's not like extra parts count as flaws, so enjoy!
