A balance sport, Slacklining utilizes nylon webbing stretched tight between two anchor points. It is distinct from tightrope walking in that the line is not held rigidly taut — it is instead dynamic, stretching and bouncing like a large rubber band. The line's tension can be adjusted to suit the performer and different types of dynamic webbing can be used to achieve a variety of feats. The line itself is flat, due to the nature of webbing, therefore keeping the slacker's footing from rolling as would be the case with an ordinary rope. The dynamic nature of the line allows for imposing tricks and stunts.
Goombas reappear in the game New Super Mario Bros. Wii , acting the same as the ones from New Super Mario Bros. Big Goombas also reappear, but rather than being big like in Super Mario Galaxy , they have the same size as in Super Mario Bros. 3 . A new variant, even larger than a Big Goomba , makes its debut, the Mega Goomba , who is somehow similar to a boss from New Super Mario Bros. The Goomba, Big Goomba, and Mega Goomba can be encountered in the Enemy Course of World 1 . In this Enemy Course it can be either eight Goombas, four Big Goombas, or two Mega Goombas. Also, during the boss fight with Kamek , his magic can transform the platforms into Goombas, in addition to a variety of other enemies.
