World 2 (Dr. Mario World)

World 2 is a desert world in Dr. Mario World. It introduces bubbles which can float upwards and Virus Coins which are background objects that require removing all non-capsule objects to collect. The second area introduces colored cages where eliminating the lock blocks of that color removes them.

When an area is cleared, Spikes and Pokeys appear. The viruses featured in the regular stages are red, blue and green.
