Syrinscape—Bulette Battle SoundSet

From the Pathfinder Bestiary: The creation of some unknown arcanist in millennia past, the bulette has bred true to become one of the fiercest predators of the hills. Burrowing rapidly through the earth just beneath the surface, sometimes with its armored fin cutting a distinctive wake behind it, the bulette launches itself free of stone and soil to tear into its prey without remorse, giving rise to the common appellation "landshark."

Bulettes are notoriously foul-tempered, attacking far larger creatures with no regard for personal safety. Solitary beasts except for the occasional mated pair, they spend most of their time patrolling the perimeters of territories that can stretch up to 30 square miles, hunting game and punishing interlopers with a fury that shakes the hillsides.
