The aliens land their craft on a small lake with uninhabited islands.
They observe the surrounding area and don’t see much going on.
The aliens scrutinize the half-dozen islands around the spaceship, how the islands look deserted and the land is brown and barren. It’s possible there are microscopic life forms present, but besides the islands there’s nothing distinctive.
The lake is crystal clear with some sort of clay bottom. There are no life forms visible in the water.
A giant whirlpool develops and sweeps the spaceship away.
Andrew, unaware of the flying saucer, flushes the toilet again for good measure.
