Timer Challenge
Timer Challenges are challenges that spawn temporary platforms when activated, and involve traversing said platforms before a timer runs out, typically to collect a Power Moon that is also temporarily spawned by the challenge. Timer Challenges can be activated by placing Cappy onto a scarecrow, stepping on a P-Switch, or activating a ground pound switch. Some Timer Challenges spawn a key, which in turn spawns a Power Moon that will likewise disappear when the timer runs out.
