Wonder Effect

Wonder Effects are the central mechanic of Super Mario Bros. Wonder, triggered by collecting Wonder Flowers. Collecting them in different levels causes various effects, including making certain pipes move up and down or bend, stretching players and enemies, transforming the player into something different like a Spike Ball, causing hordes of enemies to appear, or spawning flower coins. During a Wonder Effect, a wavy effect is added to the corners of the screen, and a decimal place is added to the flower coin counter. If the Wonder Effect has a time limit, a timer will appear at the top of the screen to show the remaining time.

A Wonder Effect ends after collecting a Wonder Seed or after the timer runs out (if present).
