Welcome! In this video walkthrough series, we will play through Super Mario Galaxy on the Wii and Switch! In it, Mario must traverse the galaxy, collecting Stars to power up Rosalina's ship and make it to the center of the universe, where Bowser is holding Princess Peach! But to do so, we'll have to sling through launch stars, feed hungry Lumas with star bits, beat several comet challenges, collect a massive amount of purple coins and even unlock a hidden second playable character in order to collect all 242 stars and save the universe! Of course, this video walkthrough will help you collect all of them and conquer this game! While it was recorded using the Wii, this walkthrough fully works with the Switch version packaged in Super Mario 3D All Stars!
This video is broken up into 70 parts, each covering a galaxy (though the hungry Lumas and trial stars are all packed into one video each). Using the time stamps and chapters, you can easily skip to whichever star mission you need help with so you can collect all 242 stars in the game! The first 35 parts cover Mario's journey and the last 35 cover Luigi's journey.
In this nineteenth part, we visit the third and final full galaxy of the Bedroom Dome (the final three domes all have three full galaxies instead of two). This dome also contains the final green trial star of the game, amounting to seven total stars that you can unlock within. If you've been following along with the guide, you can now visit the three trial galaxies near Captain Toad's ship (see Part 33 for more info). This galaxy will have you using tornadoes to climb to the top of a building (Soaring on Desert Winds), solving a dangerous puzzle over instant death quicksand twice (Blasting through the Sand, Sandblast Speed Run), racing against collapsing buildings (Sunbaked Sand Castle), controlling the height of a pillar to get a bullet bill to destroy a barrier (Bullet Bill on Your Back) and collecting silver stars (Treasure of the Pyramid).
