More Pest critters for the Infestation Event

[salix_catus]

Seems to be that we are looking at this from an antagonistic point. Maybe we should think of some that have some beneficial uses to counteract the bad to a tiny amount.

A passive spaceworm that cleans the station of clutter and gives engineers small jobs to do is pretty beneficial...
Well heres some Neutral/helpful.

How the hell did this thing get in here?

Wilo-the-wisps
This race of spherical interdimensional energy beings have come to the space station to spread a message of love and joy for all living things.
They will heal passerbys(like a medbot) and speak lots of praise.(to an annoying degree)
Any aggresive action towards them however (much expected) will cause them to shout abuse at the aggressor for being rude and then vanish.
