List of subjects affected by Wonder Effects

In Super Mario Bros. Wonder, enemies and other subjects influenced by Wonder Effects behave differently from their normal counterpart. They may gain abilities, grow, shrink, or have any difference. These can impact the gameplay of the player wildly.
While some change completely and others barely change, most of these creatures get a blue, glittery glow around their bodies, and they emit glitter particles if they move.

* Hoppos:
** First seen in the level Here Come the Hoppos, this giant one takes up most of the screen and rolls around normally. As shown by the game, it is more chubbier.
** First revealed in Cosmic Hoppos, this Hoppo gets stuck, and unlike a careless Hoppo who sits there lazily, this Hoppo’s expression is aggressive. It has angry eyes, blows steam from its nostrils, and when the player jumps on it, it send them into space.
* Bulrush: Now in a stampede formation, these Bulrush cannot be defeated or stopped in any way. The herd rushes in the same direction for a whole minute, and breaks anything in its path, including the normally invincible Flag Pole. These bulls appears in the levels Bulrush Coming Through! and Bulrush Express
