Then what about that turtle can dig up, but the camera don't follow up so you can just go in the visible cells above? And if it is not powerful enough, some other power along with swapping tile instead of digging, so it explains why he doesn't fall after digging because he doesn't let an already dig trail?
When I saw the flying turtle Caelo I tought that digging up would be his power. ^^ I also tried to click the clouds at the start as I searched how to unlock him, given his update description. I expected maybe a turtle-shaped cloud then... I wonder if I am the only one who tried that. ^^"
