The phrase does something
Type more fish please into the box and send it. Fish appear. Nothing else happens, there is no counter to beat, and people have been doing it for well over a decade.
Anything with fish in it works, which is convenient, because the phrase gets typed in about nine different shapes: i want more fish, i need more fish, give me more fish, google fish please, please more fish, google more fish. All the same request.
Pushing the page under
Drag a block down toward the seabed and hold it. Let go and it comes up quicker than it went down, because buoyancy has been building against you the whole time you held it. Small blocks pop, big ones lumber.
The fish move as a group. Push into the middle of a shoal and it splits, drifts, and closes again behind your cursor. They are not smart, they are just checking what their neighbours are doing.
Spelled wrong constantly
Google onderwater, google andar water, google under the water, google in underwater, underwater google, underwater search. The autocorrect handles all of it. Google underwater sea and google underwater gravity turn up too, usually from people trying to remember whether the one they saw had fish or just floated.
Dry equivalents: floating google lifts the same layout with no water at all, and google gravity does the opposite.
