I caught a starfish(ocean critter) at the farm for some reason (Steam PC)

behind a coop building to be specific.
I noticed that question mark insect awareness icon and used my net to see what it was because I've never seen an insect spawn at the farm before, and turns out It was actually an ocean critter of all things

Hi @warm seal could you tell us how many times you encountered the issue in a season? Also, could you explain what you were doing before you found the problem?
