|align=left|The objective of this stage is to eliminate all viruses (24), including any that appear from flasks.

This stage introduces flasks, which shoots out random objects at empty spaces if a capsule landed without making a match. The random objects vary by stage, so in this stage for example, the random objects could be viruses or [[Exploder|exploders]]. Moreover, larger flasks shoot out more objects compared to the smaller flasks. Each empty flask will fully fill after 5 capsule landings.

|align=left|The last stage of the first area, the objective of this stage is to eliminate all viruses (23), collect all coins from Coin Blocks (12) and collect all purple coins (6). 

In this stage, purple coins are surrounded by crates and colorful crates. The four Brick Blocks at the beginning of the stage are Coin Blocks. At the top-most portion of the stage visible only after the stage scrolls far enough, red viruses locked behind red cages in the shape of a "P" appear, with the lock block being located at the top-left corner. Brick Blocks cover most of the space except for the bottom row in that formation. 

Purple coins are unlocked in the following sequence:
# The 3 half-frozen coins above the red colorful crates.
# The 3 fully-frozen coins below the yellow colorful crates.

This stage will scroll for one line each time enough objects are cleared or enough capsules are added to the stage and will stop after 8 lines are introduced.

When cleared, the rest of the first area in the world map gets cleared of viruses. Players also obtain the [[Goombrat]] assistant upon completing this stage.

Prior to version 2.0.0, the stage layout was different. The following changes were made:
* Capsule amount is increased from 40 to 45.
* This stage is shifted up by two rows, and as a result, the scrolling will stop at 8 lines instead of 6 lines.
* Four of the colorful crates surrounding the half-frozen coins have reduced durability. 

Prior to version 2.1.0, the stage layout was different. The following changes were made:
* Capsule amount is increased from 45 to 48.
* The first and last colorful crates in the bottom-most row are replaced with crates (1 hit to destroy). 
* The second colorful crate in the topmost row (before the stage scrolls) is replaced with a virus of matching color.
* The virus in the row visible after the stage scrolls twice is moved one row below, replacing a colorful crate.

In this stage, viruses are arranged in five separate columns with Empty Blocks in between, and each column contains one dust virus each. Two columns of six Brick Blocks are located in the second and eighth columns. Flasks of different capacity are found, meaning from the beginning of the stage, it will take less unmatched capsules to fill any that started with more capacity.

|align=left|The objective of this stage is to eliminate all viruses (45). 

In this stage, there are three groups of viruses in the shape of crosses, along with a group of viruses in the seventh to tenth rows. The filled flasks in this stage will shoot out crates that require between one and four hits to destroy.

Prior to version 1.2.0, a bug exists where the flasks will fill even when covered in dust.

Prior to version 2.0.0, the stage layout was different. The following changes were made:
* The flasks are no longer covered in dust. Flasks covered in dust cannot fill until the dust is cleared. 
* The first and last viruses in the first row are changed to dust viruses.

* Capsule amount is reduced from 40 to 37.
* The Coin Block in the sixth row is removed.
* The Brick Blocks that contain hidden viruses from the fourth row to the eighth row are no longer there, resulting in regular viruses.

|align=left|In the final stage of this world, the objective is to eliminate all viruses (63) and collect all keys (20). 

It starts out with two separate rows of Brick Blocks containing keys either directly above a door or one virus between the key and door. After the two sets of keys and doors, there are two keys with doors directly above them in Brick Blocks. Above the row where the final doors are located are flasks. The rest of the stage contain hidden viruses in Brick Blocks, dust viruses and regular viruses alongside crates. The filled flasks in this stage will shoot out Brick Blocks. 

This stage will scroll for one line each time enough objects are cleared or enough capsules are added to the stage and will stop after 11 lines are introduced.

Once it is cleared, the remaining area of the stage map gets cleared of viruses, and players can access [[World 10 (Dr. Mario World)|World 10]]. Upon completion, players earn a free [[Staff ticket|Staff Ticket]].

Prior to version 2.0.0, the stage layout was different. The following changes were made:
* Capsule amount is reduced from 50 to 39.
* The stage is shifted up by two rows, and as a result, the scrolling will stop at 11 lines instead of 9 lines.
* At the third and fourth rows from the bottom-most row of viruses, the viruses and doors are rearranged into a checkered pattern.
* On the topmost row after the stage scrolls up twice, two viruses are added in the empty spaces in the same row as the keys between Empty Blocks.

The capsule amount is increased from 39 to 41 since version 2.1.0. Besides that, this stage is otherwise the same.
