Flip Panel
Artwork of Mario flipping a Flip Panel from Super Mario World
Flip Panels first appear in Super Mario World, exclusively in #1 Iggy's Castle. They are objects attached to fences that, when hit, rotate the player and Climbing Koopas onto the other side of the fence.
When climbing on vertical Flip Panels, the player must press to flip the Flip Panel but when climbing from the bottom of a horizontal Flip Panel, the player must press instead. To flip a horizontal Flip Panel from the top, the player must perform a Ground Pound.
Flip Panels reappear in New Super Mario Bros. In this game, they also come in two different sizes; while the small ones have dimensions 2×2 and take roughly a third of a second to flip over, the large ones have dimensions 12×4 and take roughly three-quarters of a second to flip over. While two large ones appear in World 3- along with a small one in the area with the level's third Star Coin, numerous small ones appear throughout World 4-.
Flip Panels return in New Super Mario Bros. Wii, behaving the same as in New Super Mario Bros., though the small ones now have dimensions 4×4. Though eighteen appear as the basis of the Power-up Panels minigame, only three others appear in the entire rest of the game, all of which are found in World 4-: a small one appears near the beginning of the level, a large one subsequently appears just after the level's first Star Coin, and another small one appears just before the Warp Door leading to the midway point.
Notably, a particular glitch involving the large Flip Panel exists in this game; if the player uses an Ice Ball to freeze a Climbing Koopa, then flip the Flip Panel while the Climbing Koopa intersects it, the Climbing Koopa will fall to the ground and produce infinite coins.
Six Flip Panels appear as the basis of the Mario Party: Star Rush minigame Bowser's Fence Fury. If Bowser smacks a Flip Panel while a player is on it, they are automatically eliminated from the minigame.
