World 3 (Dr. Mario World)

World 3 is a beach world in Dr. Mario World. This world introduces Floatie Viruses, which must be matched three times and move to a random spot whenever matched. The second area introduces viruses fully encased in ice.

When an area is cleared, Huckit Crabs and Goombas appear in the overworld. The viruses featured in the regular stages are red, yellow and light-blue.
