One of the most main features of underwater-themed stages is that the majority of the stage itself takes place underwater. However, in certain games and cases (like 2-D platformer games), underwater stages are often completed on land. As an underwater-themed stage takes place underwater, the player can only swim thoughout the stage and cannot attack by jumping on enemies. Instead, they must either use Fire Flowers or a Yoshi to defeat enemies or just try to avoid the enemies altogether
