The seal is now what the killer 1 wanted, but the hunt is far from over. They need to wrap their prey 2 by the tail while avoiding its snapping jaws 3. Only them will they be able to pull it down and drown it. Side swipes create farther underwater turbulence 4, a new tactic 5. Growing bubbles gives cover for others to lunge at the seal's tail. Somehow the seal manages to reach a tiny ice floe 6. The killers 7 could easily grab it, but now this seems to become again. The seal's life hangs on a roll of the ice. Yet again, the pod joins forces to dislodge the seal. The seal seizes a chance to escape.
