New Super Mario Bros. Wii/Enemy Courses

Enemy Course is when you bump into an enemy on the map. You then enter a screen containing eight balloons and one to as many as four enemies. Collect all eight balloons and the enemies will disappear. A Toad will then appear and reward you three Super Mushrooms for freeing him.

World 1
Between two pipes are the eight balloons. Underneath are two Mega Goombas. Stomp them and they turn into two Grand Goombas. Stomping them results in two normal Goombas each. For a challenge, render the Mega Goombas down into regular Goombas before collecting the final balloon.
