I have two questions:
1. From what it looks like in the pictures, it looks like Os has a fourth set of medals; gray medals consisting of an elephant for the legs, a gorilla for the torso and arms and possibly a rhinoceros for the head if Wikipedia is correct. Now, I can understand a rhino and elephant together because of them being big, strong and having tough skin, but how does a gorilla fit into these two? I mean, the red medals consist of birds (hawk, eagle, crow (the latter two according to some old rumors)), the green medals consist of insects (stag beetle, mantis, grasshopper) and the yellow medals consist of jungle felines (lion, tiger, cheetah). So, is there any particular reason why a gorilla is paired with an elephant and, possibly, a rhino?
