Bubble machine

A Bubble Machine is an object in Dr. Mario World. Introduced in World 13, the bubble machine will turn on if objects next to it are eliminated. If the player does it again, the fan will hide a random virus in a bubble. It can also effect some items (shells, exploders, skill chargers, pop cannons, or electric exploders). Dr. Morton's skill can change them into empty blocks, causing the machine to be deactivated until the player returns to that stage.
