Switch (Wario Land 4)

A Frog Switch is an object that appears in the game Wario Land 4. A Frog Switch appears at the end of every level in the game. When Wario jumps on a Frog Switch, the switch will open up to reveal a ticking time bomb. Wario will then only have a certain amount of time to escape the level by returning to the Vortex at the beginning of the stage. If Wario can't escape before the bomb goes off, Wario will lose all the coins he earned in that level and will be thown back to the main map, making the player start the level all over again. The Switch also appear before the level on the main map. Wario would have to hit that one to open the Vortex and enter the level. The times given by the Frog Switches vary on the game mode. A complete list of times can be seen here.

Frog Switches resemble a blue frog on top of a red base that has a green and yellow trim. When the Frog Switch is hit, Wario shouts "Hurry up!" to the player, and an intense tune begins to play, which induces the player to run fast to the beginning of the level.
