In Pokémon Pokopia, what is the game’s day-and-night cycle linked to?

Pokémon Pokopia links its day-and-night cycle to real-world time.

This means the in-game passage between daylight and darkness is connected to the clock outside the game rather than being controlled only by story progression. The system supports Pokopia's life-simulation design, where habitats and Pokémon behavior are part of an ongoing world.

The game also contains multiple biomes, and later content adds water-diving areas with aquatic-themed Pokémon and furniture. The real-time clock should not be confused with a turn-based battle mechanic or a purely scripted time-of-day change. It is one of the details that distinguishes Pokopia's slower, persistent-feeling routine from a conventional Pokémon adventure.
