Blue switch (Super Mario Galaxy)

A Time Switch is an item that appears in Super Mario Galaxy 2. During gameplay, Mario or Luigi must ground pound them. Once Ground Pounded, the entire screen will turn black and white, and the music will sound sound very slow. The main effect of hitting the switch, however, is that is will slow down all the obstacles around Mario or Luigi. They can allow them to pass under a Thwomp or jump on a fast-moving platform with ease. The switches only last for a few seconds though, so the bros. must move quickly. Time Switches only appear in three Galaxys.
