Flip Panel (Chain-Link)

Flip Panels, also known as Revolving Doors or Revolving Gates, are a type of fence-based object appearing in several Super Mario games.

Super Mario World
Revolving Doors first appear in Super Mario World, exclusively in #1 Iggy's Castle. They are objects attached to fences that, when hit, rotate the player onto the other side of the fence.

Super Mario Sunshine
Revolving Gates return in Super Mario Sunshine, appearing in certain areas of Ricco Harbor and Pinna Park. One mission, The Runaway Ferris Wheel, involves Mario using a particular Revolving Gate in the latter area to defeat the Electro-Koopa King and obtain said mission's Shine Sprite.

When climbing on vertical Revolving Gates, the player must press to flip them, but when climbing from the bottom of a horizontal Revolving Gate, the player must press  instead. To flip a horizontal Revolving Gate from the top, the player must perform a Ground Pound.

New Super Mario Bros.
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 along with a small one in the area with the level's third Star Coin, numerous small ones appear throughout.

New Super Mario Bros. Wii
Flip Panels return in New Super Mario Bros. Wii, behaving the same as in New Super Mario Bros., though the small ones have dimensions 4×4. Though 18 appear as the basis of the minigame Power-up Panels, only three others appear in the entire rest of the game, all of which are found in : 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 flips the Flip Panel while the Climbing Koopa intersects it, the Climbing Koopa will fall to the ground and produce infinite coins.

Super Mario World television series
A single Revolving Door appears in the Super Mario World episode "Mama Luigi," with the baby Yoshisaur jumping through one while Mario and Luigi chase him through King Koopa's Neon Castle.

Mario Party: Star Rush
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.
