Not enough aliens in your life? Much like garden gnomes, planter aliens are made to attract actual aliens. Perhaps it is hard to ignore a simulacrum of an old neighbor or friend, and they just steer their little ufo right toward it. Who knows?
All I know is these little pieces will be a welcome addition to your potted plant, and remind you where you came from.
They are hand sculpted and glazed ceramic, of course, and have legs that you push into the dirt of your plant (i.e. they cannot stand on their own!).
