How to Get to Rolling Ball Hall: Location

Unlock the Entrance with Switches

①	②	③

The Rolling Ball Hall course can be found to the top-right of the oasis, in a room behind a wall with a Question Mark (?) on it. To gain access to this room, you will have to look for and activate three (3) switches around the area!

Once all have been activated, the entrance to the room will be revealed. Take note that there's a hidden pipe leading to Captain Toad in the area (it can be found around the bottom-right area.)

Rolling Ball Hall Wonder Seed Locations

1. Obtainable After Using the Wonder Flower

The first Wonder Seed becomes obtainable after taking a Wonder Flower and collecting the 5 Wonder Pieces along the path while running away from a spiked boulder. These pieces should be hard to miss since they are located along the path and in its safe spots.

Take care that while taking the 1st and 4th Wonder Pieces, the spiked boulder will roll back into your direction. Prepare to run by then!

How to Get the Wonder Flower

Wonder Flower Effect

To obtain the Wonder Flower that sets of the spiked boulder, continue on to the course until you find a pair of floating blocks. Jump on them and then jump onto another ledge leading to the flower.

2. Obtained by Clearing the Course

The second Wonder Seed can be obtained automatically after you clear the course.

Rolling Ball Hall Purple 10 Coin Locations

1. Found to the Top-Left of the Three ? Blocks

The edge of purple coin can be seen at top of the screen in this area.

The first Purple 10 Coin can be found at a narrow passage situated to the top-left of three (3) Question Mark (?) blocks. You can reach this passage by climbing on those blocks and then jumping into the passage.

Take care that a spiked ball will roll out of this narrow passage. Wait for it to come out first to enter the passage safely!

2. Enter an Underground Passage as an Elephant

The second Purple 10 Coin can be found in a hidden lower area where its passage is covered by two brick blocks. Use the Elephant Trunk to destroy these blocks and crawl into this underground passage.

Once inside this passage, simply jump over to the floating Purple 10 Coin. Take care that there will be an enemy roaming under it (watch out for glowing eyes)!

3. Found Before the End of the Course

The third Purple 10 Coin can be found as you approach the end of the course, right after the end of the Wonder Flower effect. You will find the coin under a narrow passage where a spiked boulder passes through back and forth.

This one is easy to grab! Pay extra care to the movement of the spiked boulder just in case.

How to Reach the Top of the Goal

Use the elevated platform right before the flagpole to reach its top. For safety measure, use the R Button while in midair to extend your jump distance!
