The receiving pipe
|Ability||Fire coloured fireballs|
Pipes are used as entities in Knuckleheads.
Pipes appear as cylindrical tubes. There are two types of pipes: receiving pipes and sending pipes. The sending pipes have a light on them, while the receiving pipes lack one.
Pipes fire coloured fireballs. They appear attached to the ground or walls wherever fireballs are fired, the fireballs fired are also received by pipes. The coloured light active tells the player which type of fireball is fired. Pipes cannot be turned off or destroyed, and pipes with no light on them receive fireballs.
