Earth Giant is rare yet very annoying. The creature acts in many ways like a weed. He picks the nicest spots in the forest, digs a hole and roots himself to the ground.
He is eating everything within his reach and poops extensively contaminating the soil, destroying the forest's flora.
A small "Unkraut" (as it is commonly called) usually can be uprooted by a party o 3 or 4 men and a stong rope. But when dealing with a bigger ones sometimes rural communities have to hire a professional to help.
Here is an awesome poem about Unkraut by
Through an ill tree clearing cold,
A fungus in a forest bold,
Unkraut slouch and taint the earth,
Barring any verdant birth.
