Flip Panels are an object featured in a few Super Mario series and Mario Party series games. They first appear in Super Mario World.
Description[]
A Flip Panel is a part attached to a Chain-Link. Mario or another playable character can punch it to have it rotate them over to the opposite side of a Chain-Link. A Flip Panel can be used from either the front or the back. In the 2D Super Mario games, whenever Mario or another playable character uses a Flip Panel to go behind a Chain-Link, they can only grab on to Chain-Links from the back unless they use a Flip Panel to flip back to the front.
