Hey there. Well my big Ally is the same size as Sk8tr009's Ally. He or she is about 8 inches. My little hatchlings are about an inch to an inch and a half. One of the new pink ones has his mouth open right now. Which this makes it the second time since Thursday that I've seen him with his mouth open. The other I've only seen once with his mouth open. And my other two regular colored ones they always have their mouths open. And if I remember correctly I believe the guy from P&J's said his gold or yellow adult ally's were from the pink variety. But I could be mistaken. Any ways thanks a bunch.
