A Venusian is a furry, bright pink alien who can drop from outer space directly onto the surface of the Earth. This sudden arrival can cause some inconvenience, which ends when the Venusian abruptly leaves the drop site. The Venusian's language appears to consist entirely of the syllable "Eep".

The only known sighting of a Venusian on Earth occurred during the Sesame Street song "Something Always Comes Between". The alien's arrival is one of the many obstacles that comes between a pair of lovers, dropping between the two before running off.
