The Lake is a stage in The King of Stories and does not represent any universe. It is identical to the The Lake from Brawl. Samus, Little Mac, Donkey Kong, Diddy Kong, Captain Falcon and the Excitebiker are playable in this level.
The stage is very similar, almost identical to that of Brawl with the same name. It is an open forest-like jungle, with many waterfalls, green valleys and wooden bridges, a very calming and relaxing background view. Mountains can also be seen in the background. The level is mostly consisted of water and bridges. The bridges contain many enemies to defeat and will sometimes break. In addition, players can also enter underwater caves and trees.
