UFOs

This article is about the Classic Trilogy UFOs. For the UFOs in Planet of the Z-Bots, see Z-Bots#UFOs.

UFOs and a UFO Mothership.

UFOs are moving enemies that shoot Fireballs. When UFOs collide with an object or a tile, such as a Wall, a Coin or another enemy, they turn in their preferred direction if possible; if not, they turn in a different direction. If a Stinker is lined up with a UFO horizontally or vertically, it will shoot fireballs at that Stinker. 4 UFOs each are generated by UFO Motherships if all of the UFOs present in the level get destroyed. Their movement is faster than a Coily and slower than a Kaboom!.

UFOs can float over Water and Lava, but are blocked by Empty Space. Because they are floating, electricity cannot destroy them, but spikes can.

Appearance

UFOs are blue with several yellow lights on their edges. They make a sputtering sound about every 1.5 seconds.
