One fish biologist has made it their mission for 2025 to catalog the fish from theAnimal Crossingfranchise alongside their real-world counterparts. TheAnimal Crossinggames focus on the anthropomorphic villagers that players share their islands with, but the series also has its share of land and sea critters. Throughout the different games, players have been able to capture and catalog these animals in the in-game museum.
