Co-Star Luma

“Ya know, a friend with another Wii Remote can join up with you! Then one of my Co-Star Lumas can help out!”

—Lubba, Super Mario Galaxy 2

The Co-Star Luma is an orange Luma that appears in Super Mario Galaxy 2 as a playable character and in the game's logo. The Co-Star Luma appears alongside Mario in the cooperative two-player mode known as Co-Star Mode, in which the second player is able to control it using the Wii Remote. Once it appears, it will follow behind Mario in the same manner as one of the mini-clouds that appear when the Cloud Flower is in use. If the Cloud Flower is actually in use, the Co-Star Luma will always follow Mario behind the last mini-cloud that trails Mario's head, as opposed to directly behind him like it normally would.

The Co-Star Luma can perform moves such as spinning, in addition to collecting and shooting Star Bits just like the first player can. The Co-Star Luma can also perform other actions that a single player cannot, such as temporarily immobilizing certain enemies or barriers and picking up far-away objects, including 1-Up Mushrooms, air bubbles (when underwater), and coins, which the Co-Star Luma will then bring back to Mario. The Co-Star Luma can also perform a variety of other actions: this includes activating switches or other objects; touching thorny flowers and causing them to retract their spikes; and spinning most Lumas (excluding Lubba and the Hungry Lumas) or Luigi to receive Star Bits. A larger Co-Star Luma also appears on Starship Mario and tells Mario about Co-Star Mode.

The player controlling the Co-Star Luma can make sounds on both Wii Remotes by pressing various buttons on their controller:

Player controller	Button	Sound
1		A horn honk and occasionally a cuíca
		A crowd groaning
		A crowd cheering
		A coin being collected and occasionally a 1-Up Mushroom being collected
2		A Luma giggling and occasionally a longer variant
		A coin being collected and occasionally a 1-Up Mushroom being collected
		A crowd cheering
		A crowd groaning

In Super Smash Bros. Ultimate, a Co-Star Luma makes a cameo appearance on the Starship Mario spirit.

Trivia

• The Co-Star Luma is similar in function to the second player's Star Cursor (which has a slightly lighter shade of orange) in Super Mario Galaxy.
• If the Co-Star Luma is present when Mario collects a Power Star or a Grand Star, it will appear along with Mario in the "You Got a Star/Grand Star!" victory pose.
• When the Co-Star Luma is present, orange butterflies will appear in some galaxies. When the Co-Star Luma stops and spins on the butterflies, the butterflies will release 3 Star Bits and will disappear afterwards.
