Bubble viruses appear eventually, and later ice fans start to appear. Exploders later appear, and a couple of half-frozen viruses one line after that. A line of regular viruses are found near the top, with the top containing a line of Empty Blocks. This stage will scroll for one line each time enough objects are cleared, and will stop after 10 lines are introduced.

Once it is cleared, the remaining area of the stage map gets cleared of viruses, and players can access [[World 16 (Dr. Mario World)|World 16]].
