Starship Mario

"Nice spaceship, yeah? More like a faceship! Har har!"

- Lubba

Starship Mario is a Mario-head-shaped planet and spacecraft in Super Mario Galaxy 2 that is used to travel across the universe. Although notably smaller than the previous games' hub areas, it serves as the hub of the game and has, more or less, replaced the Comet Observatory from the first game. Other than its smaller size, another difference from the Observatory is that it also has changing backgrounds, the appearance of which depends on the World that it is currently in. A flock of seagulls can be seen on and around Starship Mario in the first two worlds, as well as the final world. Starship Mario is able to access different worlds by traveling through Portals between them.

While on the ship, Mario is able to explore and interact with various non-playable characters, including Lubba and the Co-Star Luma. Some other characters in the game appear after certain Power Stars are collected or a specific goal is met.

Much like Delfino Plaza from Super Mario Sunshine, Mario can ride Yoshi here. The egg which contains him is located on the "nose" of the ship, having been obtained after rescuing Yoshi in the Yoshi Star Galaxy. A small circular platform floating just above Starship Mario has many berries, and three Boards that will advise the player on how to control Yoshi. If the player eats all of the berries on this small platform, they will get a 1-Up. There is also a room under the area with the pressure switch which can only be accessed by jumping into a large chimney which leads into the room, or by going through a secret door in the bill of the ship's "cap". The room contains a large ball of light similar to the Beacon in the Comet Observatory, a telescope and some books. There are also several platforms near the edge of the room which later become display cases. Various power-ups, such as the Fire Flower and Rock Mushroom, begin to appear on display after they are used to obtain certain Power Stars over the course of the game. However, the display cases cannot be penetrated and thus the power-ups inside cannot be used. A usable Cloud Flower does appear in front of the ship's wheel after Mario has completed "Climbing the Cloudy Tower" in the Starshine Beach Galaxy, however. This is the only power-up that can actually be used onboard Starship Mario. The Toad Brigade's Starshroom also stays close to the ship. Transfer between the two ships is possible via a Warp Pad located in the ship's right ear.

After Mario collects his first Power Star, he finds himself on a rocky meteor-battered planetoid. It is captained by Lubba, who commands a crew of Lumas. After beholding the Power Star, and seeing Baby Luma's trust in Mario, he strikes a deal with Mario and hands the ship over to him, reshaping it to look like Mario's head for as long as he continues to collect Power Stars (though it actually remains this way for the remainder of the game).

The ship's main purpose, though, is to allow Mario to travel between and select galaxies to visit. To leave the ship and go to the world map, one must step up to a ship's wheel near the top, in front of which is a small weight-activated button. When pressed, the button sends the player to the World Map, from which they can select galaxies to visit. If the game was turned off, then the player instead will go to the Grand World Map from which the player can select Worlds to visit. If the player wishes to return to Starship Mario without visiting a galaxy, they must position Starship Mario over an empty point on the World Map and then select it, which will bring up the option to return. Mario will also automatically return to the ship if he receives a Game Over at any point during gameplay. This is a significant difference from the first game, in which Mario would return to the title screen after a Game Over.

Engine Room
The ship's engine room can be entered either by entering a small door in the middle of the ship's cap, or by using the small chimney on the head of the Starship as a Warp Pipe (standing on top of it). Inside is a single Luma, whose purpose is to convert the energy from each Power Star into fuel for the spaceship. A small ball resembling the Beacon can also be found on the ceiling. In addition, as Mario completes certain missions with power-ups, they appear in the engine room under small glass domes (all except for the Rainbow Star, which does not appear here for unknown reasons). However, they cannot be used by the player, so their purpose is thought to be more for viewing purposes as souvenirs. Below are listed the seven power-ups that appear here, as well as the conditions that must be met before they will appear here:


 * Cloud Flower - Complete "Search for the Toad Brigade Captain" in the Fluffy Bluff Galaxy.
 * Rock Mushroom - Complete "Rock and Rollodillo" in the Boulder Bowl Galaxy.
 * Spring Mushroom - Complete "Spring into the Chompworks" in the Chompworks Galaxy.
 * Spin Drill - Complete "Silver Stars Down Deep" in the Spin-Dig Galaxy.
 * Bee Mushroom - Complete "The Sweetest Silver Stars" in the Honeyhop Galaxy.
 * Boo Mushroom - Complete "Haunting the Howling Tower" in the Boo Moon Galaxy.
 * Fire Flower - Complete "Burning Upside Dizzy" in the Upside Dizzy Galaxy.

Passengers
As Mario continues to explore the universe, he meets various creatures and friends. After certain missions have been completed, they appear on the ship. All creatures stand on tree stumps on the surface of Starship Mario except for the Toad Brigade, who resides on the Starshroom (accessed via a Warp Pad in Starship Mario's right ear), two Luma Shops which sell Chance Cubes for coins and Star Bits (accessed via a Warp Pipe in Starship Mario's left ear), and Luigi, who resides in a small door towards the top back of Starship Mario, and will switch places with Mario at any point after he has defeated Bowser for the first time.

Below is a full list of every character that makes an appearance on Starship Mario, as well as the conditions that must be met before they will appear. All non-playable characters make an appearance on Starship Mario, with the exception of Coach, Penguru, Piantas, and The Chimp.

"Well now...you've found quite a few of those Power Stars, huh? We'll keep track of how many ya got. That's it, the sign next to the helm right there."

- Lubba

After Mario has collected 16 Power Stars, a light blue glowing signpost appears directly to the left of Starship Mario's wheel. This sign lists all of the Power Stars and Comet Medals that Mario has currently collected, as well as the galaxies that have been unlocked thus far (and whether the galaxies have been completed or not). This sign is used to help the player keep track of how many stars they have at any various point in the game. The same information can also be accessed by clicking the "Star List" button on the pause menu at any time during gameplay.

Trivia

 * Starship Mario slightly resembles the first planet in Gateway Galaxy, as they both are covered in grass and have a similar structure at the top.
 * Whenever the player selects a galaxy to fly to from the World Map, Starship Mario will turn to look at Mario as he flies to the galaxy.
 * On the cover of Super Mario Galaxy 2, a Question Block and a Goomba both appear on Starship Mario, even though neither of these things ever appear on Starship Mario in the actual game. Also, the Warp Pipe has been repositioned, as it now appears higher up on Starship Mario's cap, as opposed to in Starship Mario's left ear.
