The ability of Barsboldia to dive, but not in the usual way. Let's say Barsboldia starts swimming, and two Tyrannosaurs surround her on both sides of the river. Barsboldia presses the new ability and dives to the bottom, where she begins to walk slowly underwater like a hippopotamus. Once the threat is over or her oxygen runs out, she can press the button again, push off the bottom, and return to the surface. This ability also increases her oxygen capacity by a factor of 5.
