Green Power Star

Green Power Stars, (or simply known just as Green Stars), are a special type of Power Star first found in Super Mario Galaxy. These power stars are very rare and typically appear under the shadow of the Green Comet, they also appear hidden in certain levels and must be found as a normal Power Star, typically, when all the Green Stars are found, hidden Galaxies are discovered.
==Profile==
Green Power Stars are shaped like standard Power Stars. Hence the name, they are colored green. In the Super Mario Galaxy series, Green Power Stars add up to the Power Star counter.
==Appearances==
===Super Mario Galaxy series===
===Super Mario Galaxy===
Green Power Stars made their debut in Super Mario Galaxy. In this game, there are three Green Power Stars and each of them are found hidden within a mission in a Galaxy below is a list of all the Galaxies the Green Stars are found in and what mission they can be obtained in.
*Battlerock Galaxy - Battlerock Barrage (only appears once Luigi sends a letter which occurs after one of the other Green Power Stars is found).
*Buoy Base Galaxy - The Floating Fortress
*Dusty Dune Galaxy - Blasting through the Sand
When a Green Power Star is found, a Green Luma appears in the Comet Observatory appearing around a green transparent Launch Star located near the Terrace and the Garage. Once all three Green Power Stars are found, the green Launch Star is restored and becomes usable, it launches Mario/Luigi to the otherwise unapproachable Planet of Trials, where three more Green Lumas await to transform into Launch Stars which can send Mario/Luigi to Rolling Gizmo Galaxy, Bubble Blast Galaxy, and Loopdeeswoop Galaxy, depending on which Luma he talks to. Once the game is beaten with both Mario and Luigi, a fourth Green Luma appears which takes the plumbers to the secret Grand Finale Galaxy.
===Super Mario Galaxy 2===
In Super Mario Galaxy 2, Green Power Stars can be found once Mario/Luigi collects all 120 Power Stars, beats the first mission of Bowser's Galaxy Generator a second time, and once the game's secret ending has been seen. The Green Power Stars are hinted by the Green Lumas which show up on Starship Mario late in the game, the first one shows up once 117 Power Stars are collected and the second one shows up once all 120 Power Stars are collected, the Green Lumas commonly give hints about the Green Power Stars often referring to them as Cosmic Jewels.
Every single Green Power Star is summoned by Green Comets, which swarm all of the galaxies after all 120 Power Stars are collected. These Stars are hidden throughout each of the Galaxies, with one Green Power Star for every Star in a galaxy. For example, if there are three normal Power Stars in a galaxy, there will be three Green Stars, making a total of six, these Green Power Stars are usually well hidden and are often off edges, in dangerous locations, or require some tactical maneuvers to obtain them, a twinkling sound can be heard when Mario/Luigi is close to a Green Power Star. Once all the Green Power Stars are collected in a Galaxy, the Silver Crown indicating that all the Power Stars in a Galaxy have been collected will change gold in color.
All 120 Green Stars are required to unlock the final galaxy of the game, Grandmaster Galaxy, which is the only galaxy that does not have Green Stars.
===Super Mario 3D World===
In Super Mario 3D World, while Green Power Stars don't appear a similar item called the Green Star does, Green Stars are effectively the replacement for Star Medals, and by extension, Star Coins. There are 380 Green Stars in all for this installment. 
To unlock the twelfth and final World, World Crown, one must collect all three main collectibles of the game from the past eleven Worlds, with 342 Green Stars being needed to help unlock World Crown.
==Trivia==
*In Super Mario Galaxy, even though only three Green Power Stars are able to be recovered in the game, a total of seven Green Lumas can be found on the Comet Observatory and the Planet of Trials (counting the one that takes Mario/Luigi to the Grand Finale Galaxy).
*Green Lumas grow up to become Green Power Stars, according to Polari.
*When the Green Comets are in orbit in Super Mario Galaxy 2, a remix of the Good Egg Galaxy's music from Super Mario Galaxy is played in World 1's map.
*When a Green Star mission is chosen in Super Mario Galaxy 2, the borders of the screen are green instead of black.
