Koopa Bros. Fortress Acting as the game’s initial dungeon, the Koopa Bros. Fortress is, fittingly enough, the domain of the four Koopa Brothers. The building was previously occupied by several friendly Bob-ombs, but they were imprisoned in the fortress’s basement when the Koopa Bros. took over. The first Star Spirit, Eldstar, is held captive in the fortress by the Koopa Bros.
Dry Dry Ruins An enormous temple that was buried for many years under the sands of Dry Dry Desert, Dry Dry Ruins is the location of the second Star Spirit, Mamar. The temple emerges from beneath the sand after Mario pinpoints its hidden location by using the tracking abilities of the “Pulse Stone.” Home to a multitude of Chain Chomps, and their master, Tutankoopa, the Dry Dry Ruins is filled with many assorted enemies, including Pokeys. It is in the Dry Dry Ruins that Mario finds the powerful upgrade to his original hammer, the Super Hammer.
Gusty Gulch Located just beyond the Forever Forest and Boo Mansion, Gusty Gulch is a small, dilapidated, village that is home to several Boos, as well as a fearsome boss – the “invincible” Tubba Blubba. The Boo inhabitants of the village are being terrorized by Tubba Blubba, who has taken to eating any Boo that he crosses paths with as a means of revenge for the harassment he endured from the Boos in the past. Once Mario discovers the weakness of Tubba Blubba, and defeats him in the Windy Mill at the base of Gusty Gulch, the Star Spirit Skolar is freed from his imprisonment by the Boos.
Shy Guy's Toy Box A toy box that is located inside of an abandoned house in Southern Toad Town, Shy Guy’s Toy Box is home to many Shy Guys, as well as the game’s sixth party member, Watt. The Toy Box shrinks anyone who enters it, so although the box is small in a literal sense, when Mario and friends are inside the Toy Box the size of the surrounding area appears to be much larger in scale. Inside of the Toy Box is a large set of railroad tracks and a train, along with several color-coded stations placed at various locations throughout the box. Mario travels to each of these stations to complete a specific task or recover a specific item, before moving on to the next station in the line. Upon defeating the area’s boss, General Guy, the fourth Star Spirit, Muskular, will be freed from his captivity and will return to Star Haven.
Lavalava Island Lavalava Island is an island located to the south-west of Toad Town, and is home to a large population of Yoshis, as well as a sizable volcano named Mt. Lavalava. When Mario initially reaches the island he must help some Yoshis in Yoshi Village find their missing children, who are lost somewhere in the Jade Jungle. Once the children are all found, Mario gains the support of his sixth party member, Sushie. After navigating through the Jade Jungle, Mario reaches the Mt. Lavalava volcano. With the “help” of Professor Kolorado, Mario is able to successfully find his way through the volcano and defeat the area’s boss, the Lava Piranha – a giant Piranha Plant that dwells inside the molten magma of the volcano and makes use of several fire-based attacks. Once the Lava Piranha is defeated, the fifth Star Spirit, Misstar, is freed.
Flower Fields Flower Fields is an isolated and secluded sanctuary of nature located in the northwestern corner of The Mushroom Kingdom. The area’s condition of endless sunshine is being endangered by the wicked, cloud-shaped menace Huff N. Puff (as well as his many underlings) who has been implementing a nefarious contraption known as the “Puff-Puff Machine” to create artificial cloud cover and block-out the sun. These actions are a direct threat to many of the residents of Flower Fields, including the plant-like “Bub-ulbs” and the Wise Wisterwood tree. Mario encounters his seventh party member, Lakilester, in Flower Fields. Lakilester is a Lakitu that was previously working for Huff N. Puff and who fought against Mario, but after being defeated by Mario, he elects to join forces with him. After Mario succeeds in toppling Huff N. Puff and clearing the air over Flower Fields, the sixth Star Spirit, Klevar, is rescued, and returns to join the other Star Spirits in Star Haven.
Crystal Palace is located in the northeast mountains of the Mushroom Kingdom. In order to reach the Palace and free the final Star Spirit, Mario must travel through Shiver City at the base of the mountain, and then climb to the top of the mountain. After Mario defeats the boss, the Crystal King, the final Star Spirit, Kalmar, is released and joins the others in Star Haven to complete the reunion. With all seven Star Spirits restored to their full power, Mario prepares to challenge Bowser in a final showdown.
