Wonder Flower

A Wonder Flower is a flower powerup that appears in Super Mario Bros. Wonder. When collected, it activates Wonder Effects, which change some mechanics in the level or transform the player. Wonder Flowers come in different colors, such as blue, red, green, and yellow.

Concept and creation
The Wonder Flower was conceived as part of an effort to introduce surprising elements that would challenge the player. The original idea was to include items that would warp players to a new area but producer Takashi Tezuka found the idea uninteresting, stating, "If you’re still just going to warp to a different area, it’s still the same. Why don’t you just change where you are right now?". . To gather suggestions for effects the Wonder Flower could have, director Shiro Mouri and Tezuka pooled the entire development team of Super Mario Bros. Wonder no matter their seniority or role on the project, receiving a little over 2,000 suggestions.
