Bubble aliens

Bubble Aliens are enemies first introduced in level 12 of Mega Mash.

Appearance
The orange aliens have a single head with eyes, purple wings on the side, antennae on top of their heads and the entire bottom of his head being covered by a mouth. The entire body of the alien is inside a bubble, which when shot by the ship damages the creature. It is possible the bubble is actually the transparent outside of the creature.

Game Information
Bubble aliens move horizontally, firing four bullets: one above, one below and two on either sides. They can be destroyed with three shots from the ship's laser beam, of which they will explode. Since the enemy attacks constantly, players may find them difficult to destroy, as they can only shoot in a horizontal direction.
