|align=left|The last stage of the first area and starting with 50 capsules, the objective of this stage is to eliminate all viruses (67) (including any that appear from flasks before this objective is achieved) and collect all keys (7). 

In this stage, the bottom four rows contain rows of viruses (normal, within barrels, half-frozen) with a gap in between each of them, and the five rows above it have viruses contained in all undamaged barrels and most Brick Blocks. Two keys and three exploders are found in a few of the Brick Blocks. Followed by this, the five undamaged barrels in a row all contain keys, along with six doors directly above them.

In the section above the doors, colorful crates are arranged in a pattern where floatie viruses and Capsule Plus are found in the larger gaps, while the lock blocks are found in the smaller gaps that unlock the colorful crates in the leftmost column, which are located below the door. The filled flasks in this stage will shoot out either viruses or viruses shrouded in dust. 

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.

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

Prior to version 2.1.0, the stage layout was different. The following changes were made:
* Capsule amount is increased from 40 to 43.
* The stage is shifted up by one row, resulting in the scrolling lasting for 11 rows instead of 10 rows.

The capsule amount is increased from 43 to 50 since June 2021. Besides that, this stage is otherwise the same.
