Time

Time flows during the World of Kirbycraft movies and Mary's Magical Adventure. It is hard to describe time, as it's thought of as another dimension.

World of Kirbycraft
During all of the World of Kirbycraft movies, each fight or scene takes place at a random time chosen by Kirby Air Ride when City Trial is loaded. No scene or fight is designed for a particular time, though events unrelated to time such as Uther's fog spell unintentionally occur at appropriate moments.

Magical Mary
In Magical Mary 1, time automatically advances in standard levels by default, starting at sunset during the first level. Due to this, no level is designed to look appropriate for just one time of day; Lights may turn on at night, and textures swap as appropriate.

If the Time of Day System is turned off, each level part will use a specific time of day, never changing until a new level loads with the system enabled.
