Cave of Shadows is a stage in The King of Stories. It is a dark, greenish cave with mysterious creatures. Zero Suit Samus, Donkey Kong, Fox, Sheriff and King Dedede are playable in this level.
The stage is inspired by a cave in The Dark Tower. It is a huge, greenish, dark cave where a race of fearsome creatures lives. If woken up during their sleep, they will become very agressive. The stage features multiple railways, meaning that it is an abandoned mine. There are also many bridges that connect multiple parts of the cave. There is also a lake of green water some feet below the cave.
