The Small UFO only appears in the special mission ¨They Came From Outer Space!!!¨ It looks like a stereotypical UFO: grey metal body, glass dome, blinking lights on the front. When popped, It spawns 10 Bleep Bloons. It is immune to all tech(this does not include sun powers and Bloon Annihilation Ability.) It is also immune to sharp objects, but can be popped by anything that pops lead.
