There are multiple variants of the candy cane fence. In some levels there are horizontal or vertical candy cane fences which take up one or more spaces. Sometimes they are linked together to protect candies and blockers within their radius. There is also the candy cane space, composed of four candy cane fences linked together so they form a 1x1 square, like most blockers. The candy cane space is specifically designed to protect individual tiles on the board. An example is level 3256, where colour bombs are needed but they are protected by candy cane spaces.
A Magic Mixer surrounded by candy cane fences is able to spawn blockers, this nature of candy cane fences was revealed in level 3394.
This blocker's main gimmick is to limit space on the board. Normally, once a blocker is destroyed then something else occupies the space(s) left behind. However, if a blocker surrounded by candy cane fences is destroyed then the candy cane fences will prevent the space from being filled by anything else.
Furthermore, candy cane fences may be used to surround blockers so that they can only be destroyed by special candy effects.
It is possible for movable elements to be transported outside the radius of candy cane fences through teleporters and conveyor belts, as seen in level 3258 and other levels.
