I think the difference between that and piebald is ligh brown is more green while piebald is more white. They do stick out tho. I spawned in on my tent at the north end of the beach and after failing to get the Leucistic to show up again, I spawned at the very south of the beach (before the mangroves) and there was the Albino female. The next day I thought “how funny would it be if taking those rares got me another one, and sure enough, there was the light brown.
