Pull Star

The Pull Star is an object that appears in Super Mario Galaxy and Super Mario Galaxy 2. It resembles a small, blue version of a Launch Star inside a blue bubble or orb. When activated, they pull Mario or Luigi towards them. Its name is a pun on.

Super Mario Galaxy
Pull Stars can be found in virtually every galaxy. When the player touches one with the Star Cursor, it uses a blue gravitational aura to lift Mario or Luigi off the ground, pulling him up toward it. Combining the power of these Pull Stars and using them in tandem can help them reach far heights or areas.

In some areas, Pull Stars are found orbiting other objects in the galaxy, such as Launch Stars or Power Stars. The player must use the right one at the right time to touch the object without accidentally "slingshooting" past it. In areas such as the Good Egg Galaxy and the Terrace, it is shown that blue Lumas actually transform into Pull Stars, in much the same way as yellow Lumas mostly transform into Launch Stars or Sling Stars.

As with Launch Stars, Pull Stars occasionally need to be assembled by gathering Star Chips. Five blue Star Chips are needed to make a Pull Star or set of Pull Stars appear.

A single Pull Star appears in every Dome onboard the Comet Observatory, where they allow the player to view the galaxies that are accessible from that particular Dome. When they select a galaxy to fly to, the Pull Star transforms into a Launch Star, which then shoots Mario or Luigi to that galaxy.

Blue Star Capsule Planets are round glass planets that have a Pull Star in their center. There are three such planets in Space Junk Galaxy and two in Ghostly Galaxy. If Mario gets pulled and held by these planets, he cannot be stationary unlike normal Pull Stars due to the shape of the planet; instead, he continuously bounces on their surface as he is getting pulled.

Super Mario Galaxy 2
Pull Stars return as common objects in Super Mario Galaxy 2, with the same role. Unlike in the previous game, none of them are formed from blue Lumas or Star Chips.

Mini Mario & Friends: amiibo Challenge
Pull Stars appear again in Mini Mario & Friends: amiibo Challenge, where they are referred to as Gravity Wells. They are present in all levels of Gravity Galaxy and the fourth level of the Star World. When tapped on the GamePad, they release a gravitational field that can pull a Mini closer. The toy will be held at the center of the Gravity Well until the player taps on it again. Gravity Wells can be used to keep the Mini safe from a long fall or pull it from behind a wall.
