Pipe interior

It has been requested that this article be deleted. Reason: Poorly written article about an arbitrary, semi-redundant concept. Similar “Pipe Rooms” already exist in various other games in this franchise. (Such as SMB1, SPM, NSMBW, SM3DW, etc.) It thusly appears that this entire article is effectively about SMG’s iteration of the concept of “Bonus rooms”. It’s also very dubious whether the name of the titular music track should count as a “proper name” for this subject, seeing as the soundtrack has various inconsistencies from the names of the areas they play in. (Most notably “Good Egg Galaxy/Egg Planet.”)
If you do not feel this article should be deleted, please explain on its talk page.

This article is about pipe rooms in Super Mario Galaxy. For other uses, see Warp Zones.

A pipe interior.

Pipe interiors are enclosed rooms in Super Mario Galaxy accessible via Warp Pipes and generally containing optional rewards. They are in many galaxies, usually containing ? Coins inside which create 1-Up Mushrooms or Music Notes. Others have enemies and require Rainbow Stars to defeat them, such as Ruby Rocks and prickly plants. The last kind houses many Brick Blocks, and is a climb up to the coin. The objective of this type is to break as little Brick Blocks as possible, as they will turn into Star Bits once the effect is on. Lamps can also be found in them.

The design of a pipe interior features multicolored bricks, some fallen off. Ruby Rocks create a circular trail on the floors and walls. The background is a swirling background that changes its colors.

List

• Good Egg Galaxy: Two exist in the galaxy. The red one is found on the bottom of the starting planet and is required to get to Luigi and King Kaliente if a Triple Jump is not used. It contains many platforms that let the player move up and down through gravity and contains a ? Coin. It contains music notes that play Underground BGM before granting a 1-Up. The other is found in A Snack of Cosmic Proportions on the Chain Chomp planet. Contains a Rainbow Star.
• Honeyhive Galaxy: One exists on top of the platform with water.
• Beach Bowl Galaxy: Underwater near the waterfall. Contains a tall area with Goombas and Brick Blocks with some Empty Blocks. Touching the ? Coin at the top turns every Brick Block and Empty Blocks into some star shards, so the goal is to break as little Brick Blocks as possible.
• Gusty Garden Galaxy: Underneath a platform on the starting planet during Gusty Garden's Gravity Scramble and The Golden Chomp missions.
• Dusty Dune Galaxy: After the Eye Beamer segment in Blasting through the Sand and Sandblast Speed Run. Identical to the Good Egg Galaxy one, but produces three 1-Ups. Transports player to the planet with Bone Twisters.
• Gold Leaf Galaxy: Found on top of the starting planet. Can easily be found if a ? Coin near a black hole is hit, which creates a Sling Star and a total of 50 coins. Inside is a bunch of Ruby Rocks and gravity ramps with a Rainbow Star.
• Toy Time Galaxy: there are two pipes. One is found in Mecha-Bowser, and requires the Spring Mushroom. Similar to Beach Bowl Galaxy's but upward. Second is in Bouncing Down Cake Lane, found on a spoon. Many spiky plants are in this one.
• Deep Dark Galaxy

Notes

• Pipe interiors are placed above the skygrid, so they are impossible to enter. However, these floating boxes can still be seen in King Kaliente's Battle Fleet and the first two missions of Deep Dark Galaxy.
