Village Underside

The Village Underside is the area under Pianta Village in Super Mario Sunshine. Mario must go there in order to beat an episode. It also has giant, bouncy mushrooms. The ceiling is made of bamboo platforms and catwalks. It's very tricky, because one slip up and you fall. The giant branches are slick unlike the ones on top, so don't expect to be saved if you land on them.

A secret area is found in the Village Underside, however, it's covered with weird Goop. Mario has to bring Yoshi here to get the Goop off. Surprisingly, Piantas live in the secret area of the underside.
