|align=left|Starting with 30 capsules, the objective of this stage is to eliminate all viruses (29) and collect all [[Key|keys]] (8).

This stage introduces [[electric exploder]]s, which will send out electric shocks to three nearby objects when matched or destroyed. In this stage, there are three rows of viruses with electric exploders in the middle, where two of them are inside [[barrel]]s. Cages are found between the keys and [[Key Door|doors]] in the second, fourth and sixth rows, with their corresponding [[lock block]]s in the barrels in the topmost row inside barrels where viruses inside barrels are also found.

In the beginning of this stage and the next two revealed rows, there are barrels at the three leftmost columns which contain exploders in the same row as the shells inside barrels, a lock block in one of the barrels in the second-revealed row and viruses in the others. Colorful crates are placed in the same row as the shells inside barrels, as well as below some viruses. All the keys are found in two spaces above, with the leftmost and rightmost keys (the latter visible after the stage scrolls) having their doors in the eighth-revealed rows.

In the third-revealed row, there are two pop cannon handy bottles. The bottles are caged along with the crates in the rest of the stage. The rest of the stage also has viruses, half-frozen floatie viruses and Brick Blocks, with the exception of the last revealed row, which 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 9 lines are introduced.

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

The capsule amount is increased from 36 to 45 since June 2021. Besides that, this stage is otherwise the same.

|align=left|In the final stage of this world and starting with 38 capsules, the objective is to collect all purple coins (41) and collect all keys (4).

At the beginning of the stage, purple coins are arranged in a checkered pattern with barrels containing viruses, flasks and electric exploders within the gaps. Both rows of barrels contain viruses. Keys are within the barrels in the first-revealed row, with their corresponding doors are within the final-revealed row, where they are also within barrels. 

Beyond the row of barreled keys, some rows contain half-frozen flasks that will not activate as long as they contain ice. The second-revealed row contains electric exploders, the fifth-revealed row contains brick Blocks containing hidden viruses and electric exploders, and the eighth-revealed row contains Brick Blocks containing hidden viruses and purple coins. In between the aforementioned rows are viruses and fully-frozen purple coins, with additional fully-frozen purple coins in the last two revealed rows. The filled flasks in this stage will shoot out viruses. 

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 9 lines are introduced.

Once it is cleared, the remaining area of the stage map gets cleared of viruses, and players can access [[World 21]]. Upon completion, players earn a free [[Staff ticket|Staff Ticket]].
