Switch (Wario Land 4)

A switch, also referred to as a timer, is an object that appears at the end of every level in Wario Land 4. When Wario jumps on a switch, it will open up to reveal a ticking time bomb, and any solid Kaeru Blocks will turn transparent and vice-versa. Wario then yells "Hurry up!", the game's theme becomes more intense, and the player is given a certain amount of time to escape the level by returning to the vortex at the beginning of the stage. If Wario does not escape before the timer runs out, his coins and score will quickly deplete. If the score reaches zero, Wario will be forced out of the level and back to the main map.

The times given by the switches vary on the game mode. In the level Fiery Cavern, the switch turns the level into ice. In Hotel Horror, there are two doors which have a frog sign on it. These doors will only open when the switch is hit.

The switch made a cameo appearance in Densetsu no Starfy 3, where Starfy and Wario must trek through the Undersea Ruins. A switch is found in the middle of the level, opening up a new area.

Trivia

 * A redesign of this switch was intended to appear in Wario Land: Shake It!, but was removed in the final version. It is still mostly functional and activates shake blocks, however.
 * Wario's "Hurry Up!" dialogue is not always the same. Wario can say "No-no-no.. Hurry up!" or "H-H-Hurry up!" as well.
