Drip Drop Galaxy

The Drip Drop Galaxy is a galaxy in the game Super Mario Galaxy. It is essentially a large planet made almost entirely of water, with a small sandy core and several floating islands. Sitting on the core of this galaxy, on the bottom of the sea, are some boulders. There is what appears to be a sunken airship, as well as a sunken Starshroom and a volcanic vent. The planet is inhabited by Penguins, Gringills, and various fish, including a pufferfish that is located inside a treasure chest. Torpedo Teds are shot from under the sea.

Main Planet
This main planet is made mostly of water with the exception of a sand core and two islands. Three Gringills patrol the waters and keep the penguins on land. Under the water are several rock formations and what appears to be a airship probably crashed by an careless pilot or was shot down. There is also a crashed starshroom that probably shared the same fate.

Giant Eel Outbreak
Giant Eel Outbreak is the only level of the Drip Drop Galaxy. Three Gringills are swimming underwater and thanks to this, the Penguins can't fish anymore because the eels are eating all the fish. Mario agrees to help out and dives to the bottom of the sea. Mario must find Koopa Shells and hit the Gringills with them to defeat them. After Mario has defeated all of the Gringills, the Power Star will appear on top of a sunken ship.

Finishing this level and collecting 55 stars will make the Bonefin Galaxy accessible from the Engine Room.
