World 3 (Dr. Mario World)

Template:Worldbox World 3 is a beach world in Dr. Mario World. It introduces light blue viruses in its regular stages, which replace blue ones. This world also 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.

Stage names in bold red text are labelled as hard stages in the game.
