well it didnt till you said it did , hm well one i wanted know if those boxes contained something more and second i dunno cuz i didnt saw much of those ingame yet
I've never used a key on these boxes and still have had pretty decent luck with them. So far I've gotten frigates in various colors, pirate captain hat boxes, pirate bandana boxes, pirate eye patch boxes, some refines (everything from hermes to low essence) and hearts (mostly white, gold and green).
Not sure what colors the frigate comes in but I've either gotten or seen white, black, yellow, pink, purple. Next to the piggie cart, this is my favorite frame
