The Green Iron Pig with the Tall Shrub
An iron, green pig shows up in Andreasberg. It has once pulled the trousers off a miner. It has a tall, green shrub on its back, and has caused a lot of damage at the Geschneiten (Dohnenstiegen). It is also prone to changing its shape. For example, it once turned into a porcupine and a bird before the eyes of a miner, and it can make itself invisible as well.
