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 Wario completes. 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 portal at the beginning of the stage. If Wario can't escape before the bomb goes off, Wario will lose the coins he earned in that level and will be thown back to the main map, making the player to retry the level.

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.
