Still on the two-fish bit, I woke up with more inspiration of what would be better and couldn’t help myself.
The two fish are at the edge of a big party. There are balloons and a whole bunch of fish everywhere who are partying. In the center of the image there’s a limbo pole setup quite low to the ground and it’s obvious fish are trying to swim under it. Above there’s a banner that says “PLP Limbo Party”
The one fish asks the other: “Why are you at a PLP party?”
The other fish responds: “I’m watching to see how low they can go”
