Penguin Pushover is a minigame in Epic Minigames. It was made by TheSteelEagle and Siriologist.
The map takes place in Antartica as that's one of the only places where penguins are inhabited. The body of water at the edge is most likely the ocean.
Players must avoid being pushed off by the stampede of penguins. When the minigame starts, not that many penguins will appear, but as the minigame progresses, more penguins will start coming down the path.
