Fence

A Fence is an object found in various Mario games, such as Super Mario World and New Super Mario Bros..

In Super Mario World, Fences occasionally appear in Castles. Mario or Luigi can jump on, climb on, and jump off of them to go around traps like Lava. The brothers can also flip to the other side by punching a square panel. Climbing Koopas are commonly found to be climbing on Fences, and they are capable of climbing around both sides of the fence. The brothers may punch the Climbing Koopas that are on the other side to kill them.

In Super Mario Sunshine, Fences can be used the same way. Many of the fences take the form of boxes which enclose enemies and coins, although some are traditionally flat. Fences appear in Ricco Harbor, Pinna Park and Pianta Village and can be used to knock off enemies from the other side.

Fences reappear in New Super Mario Bros. Wii as obstacles in Fortresses and Castles, similar to Super Mario World. Certain areas are inaccessible unless you switch to the other side of the fence, via the revolving gate.

Appearances in Other Media
A small Fence makes a brief appearance as an obstacle in Neon Castle in the Super Mario World animated series episode "Mama Luigi". Mario, Luigi and Yoshi are able to easily pass this gate by simply using its revolving door.
