	Stage 161	Dr. Baby Luigi Dr. Baby Mario	Starting with 30 capsules, the objective of this stage is to eliminate all viruses (25). This stage introduces clouds, which shroud objects behind it and will temporarily become transparent as to reveal its contents if it contains something. Any object behind a cloud behaves normally, but destroying that object will cause the cloud to disappear. In this stage, there are two groups of eight viruses shrouded in clouds above two rows consisting of Brick Blocks and viruses.
	Stage 162	Dr. Luigi Dr. Kamek	Starting with 30 capsules, the objective of this stage is to eliminate all viruses (35). The only colors available in this stage are red and blue. The upper portion of this stage is shaped like a fish formed by viruses that include normal ones, half-frozen ones and clouded ones. The lower portion of this stage contains viruses inside bubbles. Both portions have Brick Blocks. A shell is shrouded in the cloud in row #4. Prior to March 18, 2021, the stage layout was different. The following changes were made: Capsule amount is reduced from 42 to 30. The available colors are changed to red and blue only. The contents of the cloud in row #4, originally a virus, is replaced with a shell.

In this stage, clouded viruses are located at the topmost row, leftmost column and rightmost column. In the middle, an exploder is surrounded by Brick Blocks containing hidden viruses and a skill charger surrounded by viruses. The fifth cloud in the leftmost column contains a pop cannon. Prior to March 18, 2021, the stage layout was different. The following changes were made: The dust viruses surrounding the skill charger are changed to normal viruses. The clouded viruses in row #9 are removed. A pop cannon replaces a virus in the fifth cloud in the leftmost column.

The following changes were made: Some of the Brick Blocks are removed, revealing the normal viruses for those that originally had hidden viruses. Exploders are added at the corners in the first row. Brick Blocks and Empty Blocks are removed in the tenth row, except for the leftmost Empty Block. The Empty Blocks in the top-right are changed to Brick Blocks (except the corner, which has an exploder). The Brick Blocks in the middle column between the two rows of cages are replaced by one Empty Block in the higher row. Since March 18 2021, this stage is revamped, and the capsule amount is reduced from 45 to 36. Previously in this stage, there are two rows of cages, and the corresponding lock blocks are surrounded by Brick Blocks. At the higher corners are exploders. The Brick Blocks adjacent to the empty spaces in the third column and seventh column are Coin Blocks, while some of the Brick Blocks contain hidden viruses.
	Stage 196	Dr. Daisy Dr. Peach	Starting with 29 capsules, the objective of this stage is to eliminate all viruses (41). In this stage, the right portion contains viruses inside cages, with their corresponding lock blocks in the first row (one is hidden in the Brick Block) where a virus is between them. The left portion contains viruses inside bubbles and Empty Blocks. Bridging the two portions are two rows of Brick Blocks.
	Stage 197	Dr. Kamek Dr. Yoshi	Starting with 37 capsules, the objective of this stage is to eliminate all viruses (22). In this stage, there is a column of five viruses in the middle surrounded by Brick Blocks and Empty Blocks. Three lines of clouded viruses, one horizontal and two vertical are also surrounded by Brick Blocks and Empty Blocks. On the bottom-left and bottom-right are viruses inside bubbles. Prior to version 2.0.0, the stage layout was different. The following changes were made: Capsule amount is reduced from 39 to 37. Brick Blocks are removed from the top-left and top-right corners. The second to fifth rows in the third and sevent columns are changed to Brick Blocks.
	Stage 198	Dr. King Boo Dr. Fire Peach	Starting with 38 capsules, the objective of this stage is to eliminate all viruses (47). In this stage, the leftmost and rightmost columns have fully-frozen viruses, and in between the highest and lowest point of both columns are caged viruses. In the middle, there are two columns of five viruses and one lock block, and in between are three Brick Blocks (all with hidden viruses) in a column with one space apart. Prior to version 2.0.0, the stage layout was different. The following changes were made: The middle column is changed from two Brick Blocks (both with hidden viruses) and two Empty Blocks to three Empty Blocks (all with hidden viruses) each with one space apart.
	Stage 199	Dr. Fire Rosalina Dr. Fire Peach	Starting with 40 capsules, the objective of this stage is to eliminate all viruses (54). In this stage, fully-frozen viruses and a shell form the number 99 between a column of caged viruses and below a row of caged viruses and a shell. Within the first, fourth, sixth and last columns of Brick Blocks, there are 2 pop cannons, a shell and hidden viruses in the others, while the other Brick Blocks do not contain anything. A lock block is within the hole of the first "9". Prior to version 2.0.0, the stage layout was different. The following changes were made: Capsule amount is reduced from 54 to 50. The Brick Blocks in the second, third, seventh and eighth columns no longer contain hidden viruses, leaving only the first, fourth, sixth and last columns with them. Prior to March 18, 2021, the stage layout was different. The following changes were made: This stage is no longer labeled as "Hard". Capsule amount is reduced from 50 to 40. The row of caged viruses are removed in row #10, and a column of caged viruses is added to the middle column up to row #9. The contents of the cage in the top-left corner is changed from a virus to a shell, while the third virus in row #5 is changed to a shell. The contents of the Brick Blocks in row #9 are changed from viruses to pop cannons. Moreover, the second Brick Block in row #9 is moved to the rightmost part of the row. The contents of the rightmost Brick Block in row #2 is changed from a virus to a shell.
	Stage 200 (Hard)	Dr. Yoshi Dr. Fire Mario	In the final stage of this world and starting with 50 capsules, the objective is to eliminate all viruses (50). At the beginning of the stage, there are dust viruses and clouded viruses in addition to normal viruses placed around Brick Blocks and Empty Blocks. Further up the stage are floatie viruses and hidden viruses inside 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 5 lines are introduced. Once it is cleared, the remaining area of the stage map gets cleared of viruses, and players can access World 6. Upon completion, players earn a free Staff Ticket. Prior to version 2.0.0, the stage layout was different. The following changes were made: The row of Empty Blocks visible after the stage scrolled all the way is removed, moving all the stage objects one row above. The floatie viruses in the row that appear after the stage scrolls twice are changed to normal viruses.
