Manhole (Game & Watch)

Manhole is a game that originally appeared on the Game & Watch, and was ported as a minigame in both Game & Watch Gallery and Game & Watch Gallery 4

Game & Watch Gallery series
Manhole can be played in both the Classic Version, which is exactly the same as the original Game & Watch game, or in the Modern Version, which uses Mario characters in place of the generic figures.

Classic Version
The main character had to stop pedestrians from falling into holes that lead to the sewers below. To do this, he used a manhole cover, which filled in the holes long enough for the people to pass.

Modern Version
Mario, Toad and Donkey Kong Jr. are the pedestrians in this version, walking at different speeds, while Yoshi is the character the player controls. In this version, four manholes can stay up at once, unlike the original. The manholes can drop from characters stepping on them, causing the next pedestrian to fall if Yoshi does not act quickly. Yoshi can also hold a manhole in place to keep it from falling.

Super Smash Bros. series
In Flat Zone and Flat Zone 2 (from Super Smash Bros. Melee and Super Smash Bros. Brawl, respectively), the main character from Manhole appears, where his manhole cover can be used as a platform. Mr. Game & Watch also has a move where he flips a manhole cover in front of him, based on Manhole.

WarioWare series
In WarioWare: Smooth Moves, there is a microgame similar to Manhole called Bridge Work, which is found in Orbulon's stage.
