I guess secondly - we really should discuss what kinda tone we want to shoot for. For instance, an idea of other life for black comedy - a planet populated by herbivorous grey-skinned bipeds who call themselves zombees. Those who assist them are made into honorary zombees. They also have a disease transmissible between species that can cause a person to fall into a state of death for up to a week.

Humans reacted to this species as well as can be expected.
