The Frog Switch Block appears in the Game Boy Advance game, Wario Land 4. These Blocks have a frog face on it. They can either appear solid (Wario is not able to walk through/on them), or transparent (Wario is able to walk through/on them). Depending on whether of not Wario has hit the Frog Switch or not, the blocks will switch appearances (e.g. all transparent Blocks will become solid, and all solid Blocks will become transparent). Some new areas are only accessible by hitting the Frog Switch, so the player may have to find the rest of the Jewel Pieces or maybe even the Keyzer within a time limit.
