Dug up soil

Dug up soil is a piece of scenery found in the jail on the second level of Underground Pass. There are two slaves and a crate in the jail. Railings must be picklocked to enter the jail.

The soil can be searched:
 * under the soil is a tunnel
 * would you like to enter?
 * no, im scared of small spaces - yep, let's do it
 * you climb into the small tunnel
 * and crawl into a small dark passage
