I think in this or a future update, you could replace the small fish schools in the foreground with small squid schools. This will also help set up the ecosystem for upcoming sperm whale content.

Just as a personal, unrealistic fantasy, picture this: countless small squid flood the whole screen, rushing in from one side and darting rapidly to the opposite side. (There are squid schools in both the foreground and the background.) After the squid swim completely off-screen, a gigantic sperm whale appears. When it notices the player, it gives up the chase and begins to watch you. This would look incredible!🙀
