These viruses were introduced unintentionally to Niflheim by the Toymaker's creations, therefore they have been aptly named "Puppet Viruses".
This system proved unpopular, so by default it is disabled. Your creatures will receive neither the benefits nor the penalties associated with it. If you would like to enable it, you can do so under 'Player>Account>Game Options>Puppet Virus System'.
Puppet Viruses can be contracted when creatures spend time together. At birth they can be received from their parents (half the normal chance, does not affect LESPs), Battle Breeding and from the Breeding Shop. Keep in mind, however, that aside from contracting and inflicting them, PVs do not affect Battle Breeding in any other way.
PVs can be removed at Tattoo Shops. You can also overwrite a negative PV like Eye Pox with a positive one like Jungle Fever.
