Description
Injecting this agent infests your world with rodents.
"Woolmice, otherwise known as voles, are tiny omnivores that naturally live in grasslands. They are opportunistic feeders, which means that they'll happily ear any food that gets in their reach. Like most voles, these woolmice are shy and will try to back off if a Creature approaches them. They build their nests from leaves, stems and other vegetal products. If there is enough food and vegetation to support them, woolmouse populations can increase rapidly."
