No, no, no.
Many of the Shargles have a pattern in their feathers that looks like a stylised set of letters - a lower case i and an upper case G. Some of us know who that logo belongs to - but how did that logo end up on the feathers of a bird that according to the natives, has been on the Island at least as long as they have known of the paths up into the mountains?
1. Where did you get this information?
2. Actually, the Shargles were here long before the Natives arrived. Apparently, there was something of a war between the two groups, after which the Shargles either went up higher on the mountains that we could get or went into some sort of hibernation-type state, and reemerged for some reason more recently, most likely due to the appearance of the outsiders, or at least connected with that.
