Walrus

On a crowded beach or narrow ice ledge, a walrus becomes a wall of muscle, blubber and ivory. Adults rest shoulder to shoulder, and a startled group may crush anything caught between bodies and water. A bull defending space swings its tusks upward, then simply leans its weight into whatever remains standing.

Tusk Sweep: piercing, melee 5 ft, +3 to hit, 2d8+3. Every creature in a 10 ft forward arc makes a Quick save; a failed save deals the attack damage and pushes the creature 5 ft. A successful save avoids the sweep.

Blubber and Bulk: the walrus is resistant to natural cold and gains +2 Tough against attempts to push or drag it. A clear route into open water ends pursuit unless a calf or wounded member of the herd remains behind.
