Dobbsey is talking to Brainley in the lab. Brainley is staring at his BrainBook laptop.

Dobbsey: So our shipment of antique diving suits went missing en route from Australia...

Brainley: No time to worry about that now! A rogue group of nanognomes are turning marsupials into zombies.

Dobbsey: ...you don't think those two events are related, do you?

Brainley: I certainly hope not.

Cut to an underwater shot of two zombie koalas in old-fashioned diving suits wandering across the ocean floor. Their eyes glow bright red, and they are walking with arms stiffly extended, suit hoses trailing offscreen. There is coral in the background, and sea grass in the foreground. The zombie in the foreground is walking menacingly up to a brain coral.
