The Mushroom Course is a golf course in Mario Golf: Advance Tour. It is unlocked by completing the other four courses' tournaments and is the last tourney to go through for both singles and doubles. Once the player has every trophy from Marion to Links, Princess Peach will send the player an invitation to compete in the Mushroom Kingdom. A glowing sphere will appear in the center of the Marion Clubhouse's foyer. Upon interacting with the sphere, Toad jumps out, asking the player if they wish to proceed to the Mushroom Kingdom. Princess Peach then begins the Mushroom Tourney. Mario goes into the pipe first, and everyone follows Mario to play the tourney. The player can decline the start of the tourney and explore around the castle or go back to the Marion Clubhouse, though there are no side games in the Mushroom Kingdom. Completing the Mushroom Tourney unlocks Star Tournaments and tourney greens.
The Mushroom Course is not available in Go-Go Gates. It also has no Star variant, since it already features the kind of gimmicks that Star courses possess normally. Therefore, the only thing different about the course in Star Tournaments is the presence of tourney greens.
This hole has a cluster of small floating star-shaped islands in the sky surrounding a larger one, which houses the green. The area around the green resembles Mario's face, with the nose serving as the green.
This hole features more islands in the sky. Mushrooms and star-shaped bunkers serve as obstacles. The green is also star-shaped.
Small, circular water hazards containing Piranha Plants are found near this hole's narrow fairway. If the ball lands in a Piranha Plant's mouth, it will spit the ball onto the grass near the water. If it hits a Piranha Plant's stem, it will fall into the water. There is a row of floating Empty Blocks at the start which can potentially obstruct tee shots. Three puddles of goop are found on the far side of the hole.
This hole takes place in a wasteland and features a double dogleg fairway that dips downhill after the first bend. Landing on the Play Panel near the first bunker will detonate the nearby Bob-ombs and the rocks beside them. There is a small patch of grass in the middle of the waste area to the left with another Bob-omb on it; hitting it with the ball will detonate both it and some other Bob-ombs and rocks near the green.
There are two sets of Bob-ombs surrounded by rocks which can be detonated using nearby Play Panels. One is on the right side of the fairway near the beginning of the hole, and one is on the left side near the green. Several Empty Blocks are floating around the area, four of which are right in front of the tee boxes.
Three pools filled with Piranha Plants are found on this hole. There is one by the tee boxes, one to the left of the fairway, and one south of the green. A large goop puddle lies ahead of the green and may catch shots that overshoot it.
This hole's fairway is narrow and curves slightly to the left. A row of four Bob-ombs with rocks behind them are in front of the green. Each individual Bob-omb is tied to a Play Panel detonator. Three bunkers surround the green.
This hole takes place in a volcanic area with a narrow, winding fairway. Multiple flame-shaped lava hazards are found here, and a larger lava pool houses a small island with fairway on it that can be used to get tee shots closer to the green.
Mushrooms, beanstalks, and Pokeys feature prominently on this hole. There is a Thwomp floating between two Pokeys on the left and another between two beanstalks on the right. The land beneath the Thwomp on the left is risen by default, while the land beneath the right Thwomp is lowered. Landing on the Play Panels causes the Thwomp above the risen area to slam downward, alternating the height of the two platforms.
Lava pools lie on both sides of the fairway near the middle. Three Chain Chomps are found on the latter half of the hole; if the ball lands in their territory, it is counted out of bounds.
This uphill hole has many Bob-ombs and floating Empty Blocks surrounding the area. A small river runs through the hole and borders the green on its top and left sides.
This hole features a dogleg right fairway covered with Play Panels and a lone Chain Chomp near the far end. The green is on a small island on the right side of a lava pool. If the ball stops on one of the Play Panels, it will make the volcano in the top right corner erupt and move the island to the center of the lava pool. Landing on another Play Panel will erupt the other volcano and move the island to the left. If more Play Panels are landed on afterward, nothing will happen.
Five circular pools of water appear on this hole, with two of them having Piranha Plants coming out of them. Landing on one of the two Play Panels causes Piranha Plants to come out of the other three pools and the ones already present to duck underwater. Landing on one again reverses the process. Three small puddles of goop are found near the green.
A large body of water splits the hole into two segments, with the first segment going north and the second going east. Many bunkers are found throughout, including three which surround the green. Pokeys and beanstalks line the sides of the fairway, which has four mushrooms and two Play Panels near the end of the first segment. A Thwomp hovers over a mound near the water's edge next to a Pokey. Landing on one of the Play Panels causes the Thwomp to slam into the mound, lowering it and causing a small island with a mushroom, fairway, and two bunkers to surface nearby. Landing on Play Panels after this does nothing.
The green is on the edge of an island in the middle of a lava pool. There is a Chain Chomp near the tee boxes and two near the green.
Mushrooms appear on this hole's fairway, which curves to the left and gets narrower toward the middle. There are two Play Panels near a mound with a Thwomp and two Pokeys. Landing on the Play Panels makes the Thwomp to slam the mound down, causing the small island with the green on it to rise upward, revealing it to be larger. Any subsequent landing on Play Panels does nothing.
This hole returns to the sky setting of the first two holes. Mushrooms and bunkers shaped like stars and crescent moons dot the fairway. The green is on a star-shaped island which moves to the right upon landing on one of the three Play Panels. The island will only move once.
This hole consists of seven floating islands, though only four of them have fairway to land on: the starting island in the south, the winding western island, the star-shaped island near the center with small patches of fairway on its points, and the small northwestern island that contains the green. Landing on one of the three Play Panels at the end of the starting island causes the star-shaped island to move closer to the starting island and western island. Landing on them after this happens does nothing.
