Road

Roads are objects that Mario can use in Donkey Kong for the Game Boy. When Mario jumps at a Road block, the game freezes and the player has to place the Road to any free point in the level. The road will then expand to the left and to the right of the chosen point as much as it can. The Road acts as a platform that Mario can stand on, throw the key onto and can climb on with an (also placed) Ladder. The Road can also act as a ceiling for the many enemies in the game that climb up walls and across ceilings.

Roads are timed and disappear after the time has passed. This timer indicated with a music that starts playing as soon as the road is placed and gets faster gradually. The timer can be reset to 0 if Mario places another Road within the first Road's time limit, or any other placeable objects such as Ladders, Springs and blocks. After disappearing, the Road can then be placed with the Road block again.
