Li'l UFOs are enemies in EarthBound. They are mechanical enemies that look like small silver-grey UFOs, with beady black eyes. Li'l UFOs are first encountered by Ness in Peaceful Rest Valley. They attack with beams, which can deal moderate damage to Ness and co. Li'l UFOs may also inflict the Cold status ailment, via "a beam that causes night-time stuffiness." They can appear alone or appear alongside a Spinning Robo. They are one of the few mechanical enemies in the game that don't use the song: Battle Against a Machine.

This enemy could have been inspired from the Li'l Saucers from Mother as both enemies have similar names and designs.
