Gavin kept swimming as the dolphin slipped right up to him. But at the last moment, it turned and stabbed its beak into his ribs. His breath shot out and he inhaled water. Before he could even cough it out, the dolphin emerged again from nowhere and hit him again, cracking a rib. He flailed, gasping for breath. Then it hit him again, this time smacking his head. Dazed, he sucked up a lungful of water. He lost consciousness.
