|align=left|Starting with 35 capsules, the objective of this stage is to eliminate all viruses (26) and collect all keys (3). The only colors available in this stage are red and green.

This stage introduces [[key]]s, which float to the top of the stage until it collides with an object, and will not disappear until it comes into contact with a [[Key Door|door]]. Hidden viruses are found in the third and fourth rows of [[Brick Block]]s.

Prior to March 18, 2021, the stage layout was different. The following changes were made:
