Outside the Beach Door there is a HUGE slopping and the door (and wall) crash open.

It's a fully grown Sperm Whale, deadly enemy and sworn foe of the Giant Squid.

"Have at you, squiddy old top!" the whale says in a basso VERY profundo voice. "Nemesis has arrived!" and with a lurch the whale (now seen to be a very definite male) flops toward the Giant Squid.
