Pollination Technician

A Pollination Technician is a member of an alien civilization, who can be referred to as any member of the crew of the UFOs that abduct Sims stargazing through a telescope at night. A Pollination Technician is the other parent to alien babies caused by abduction. They can impregnate male Sims with advanced technology.

Each neighborhood has its Pollination Technician. The Pollination Technician doesn't actually exist as a Sim in the game, but as a set of DNA that is passed on to alien children.

The numbered Pollination Technicians can only be found in family trees for pre-created families. If your own Sim is impregnated by a Pollination Technician, it will be anonymous.

The Pollination Technician can be removed from the family tree of an offspring alien. Though to do this, he/she must be taken away by the Social Worker. The Technician and the father will both be replaced by the mother and father of the other family. Programs as SimPE can be used to remove Pollination Technician from the family tree, though.

Trivia
In the Swedish translation of the game he has the number 11 in the end of his name.
