Manhole

Manholes are holes or sewers that are located in various places in Super Mario Sunshine. Most are found in the Delfino Plaza, but some appear in other levels, such as Ricco Harbor. Manholes lead to the intricate underground sewer system, and can lead Mario to places he cannot access aboveground, as well as to coins and other items. To access it, Mario must Ground Pound on a manhole. The manhole covers, which have a sun on them originally, when Ground Pounded, will flip, revealing a moon. When underground, a remix of the underground theme from Super Mario Bros. will play. To get out of a manhole, Mario must jump below a manhole cover. Manhole covers can also be seen in the Delfino Plaza stage in Super Smash Bros. Brawl but they serve no purpose.

In other games, they are used by Rocky Wrenches as shelter.

Trivia

 * Although Manholes are not seen in Noki Bay, the same music is played when Mario walks through the tunnel in the side of the cliff.
