'''Rolling-Ball Hall''' is a cave level in [[Sunbaked Desert]] in ''[[Super Mario Bros. Wonder]]''. It is unlocked by standing on the three buttons with [[? Block]] symbols on the world map, which will open a large door leading to this level. Clearing it unlocks [[Break Time! Revver Run]]. This course houses two [[Wonder Seed]]s, and has a difficulty of two stars.

==Layout==
The course starts with three [[Spike Ball]]s falling from above, rolling to the right and destroying a few [[Brick Block]]s. The ? Block here will give the player an [[Elephant Fruit]] if they are not [[Small Mario|small]]. To the right is a downward sloped corridor where another Spike Ball will chase from behind, taking out a few [[Goomba]]s along the way. After avoiding some more Goombas and an incoming Spike Ball, the player will make it to an area with [[Revver]]s and Brick Blocks positioned for them to destroy and open up new paths. Next is another downward sloping tunnel with a few Goombas, leading to a wall of Brick Blocks which will promptly be broken through by a Spike Ball that the player must dodge. Touching the [[Checkpoint Flag]] and falling down the hole will lead to the area where the [[Wonder Flower]] is.

To reach the Wonder Flower, which is floating at the top of the screen, the player can go to the right and jump on some Brick Blocks to access the ceiling. Collecting it will start the [[Wonder Effect]], which causes the level to tilt, spawns five [[Wonder Token]]s, and changes the level's colors from purple to yellow. Giant Spiked Balls will start to roll towards the player and break the Hard Blocks containing them; at this point the player must run or slide to get away. The tilt orientation will change a few times during this Wonder Effect, resulting in the player having to run away from another [[Giant Spiked Ball]]. The second Giant Spiked Ball will break the stone blocks on the left side of the room, opening up a hole for players to fall down. Once they reach the bottom, a third, much larger, Giant Spiked Ball will roll in from offscreen, this time destroying the level terrain. Clearing this section will lead to a pipe that takes the player to a room with the final Wonder Token, and, if all five are collected, the [[Wonder Seed]]. This room appears to be part of an ancient stone structure and features statues of [[Poplin]]s and [[Wonder Flower]]s. Taking the exit pipe will lead to the area shortly before the [[Goal Pole]], where there are more Goombas and Spike Balls destroying Block Blocks. There are Brick Blocks that can used to reach high a high up semisolid platform before the Goal Pole, but the players must be quick, as a Spike Will will roll up from behind and destroy the blocks.

Although the two large stone blocks on the left side of the final room are meant to be destroyed by a Giant Spiked Ball during the Wonder Effect, it's possible to knock one of the regular Spike Balls into said blocks while in [[Elephant Mario|elephant form]]. If this is done to access the area without activating the Wonder Effect, there will be more [[Talking Flower]]s rather than just the one next to the Wonder Seed, and they will act bewildered and chastise the player for sequence breaking.

===Hidden Character Blocks===
*A [[Princess Daisy|Daisy]] [[Hidden Character Block]] can be found above the first (from the left) row of [[Brick Block]]s guarding the third [[10-flower coin]], floating six blocks above the platform covering them all. It contains a [[flower coin]].
*A Toadette Hidden Character Block can be found just before the Checkpoint Flag of the level. It is located on the center of the ceiling of a small cranny that a spike ball rolls through, and then destroys a wall made of [[Brick Block]]s. It is a [[Coin Block]].

==10-flower coins==
*'''[[10-flower coin]] 1''': Found above the area after the first corridor where the player runs away from a [[Spike Ball]].
*'''10-flower coin 2''': Found in a dark underground area accessed by using a [[Revver]] to break some [[Brick Block]]s.
*'''10-flower coin 3''': Found underneath a platform and surrounded by Brick Blocks before the end of the level, which will be destroyed by a rolling Spike Ball.

==Trivia==
*When the level tilts for the Wonder Effect, the player character tilts along with the level and gravity continues to work perpendicular to the ground, giving the impression of the player jumping and falling at an angle. This suggests that the effect is achieved by simply tilting the camera rather than the level geometry itself.
