Meeshuu

Meeshuu is a passive night vermin that barely behaves like an animal. It stands in place and does not patrol.

The important practical detail is collision. Meeshuu has no normal collision body, so ordinary direct damage does not land the way players expect. In most cases it becomes scenery as soon as it is placed.

The main exception is acid rain. Under Leviathan weather, an uncovered Meeshuu can melt for 1 damage every 3.5 seconds. If it dies, it always drops an archangel capsule.
