Climbing Koopa

Fence Koopas are Koopa Troopas that climb fences. They are found in Super Mario World and New Super Mario Bros. Wii.

In Super Mario World, Fence Koopas are found in castles and come in two colors: red and green. The red moves faster than the green. They move in one direction, either horizontal or vertical. When they reach the edge of the fence, they will flip to the opposite side of the fence. They can be easily killed by fireballs, punches from the opposite side of the fence, or simply having the player be on top of the koopa as it passes by.
