In the final stage of this world and starting with 35 capsules, the objective is to eliminate all viruses (47) and break all Brick Blocks (53).

In this stage, the Brick Blocks at the beginning (some in bubbles) are in the formation of an arrow pointing upwards, with viruses and a bubble containing a blue lock block inside and three electric exploders below it. The Brick Block directly above the middle electric exploder contains a hidden exploder. Around the arrow's head are two layers of clouded viruses, and above the clouded viruses are two layers of blue cages that contain blue viruses and a red lock block. The red lock block corresponds to the layer of red cages above the layer of blue cages. Above the layer of red cages are Brick Blocks, in which some of them are fully-frozen. The Brick Blocks that are not frozen may contain hidden exploders and hidden floatie viruses. The last revealed row is a row of Empty 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 7 lines are introduced.

Once it is cleared, the remaining area of the stage map gets cleared of viruses, and players can access World 22. Upon completion, players earn a free staff ticket.
