The Boxed Ghost was trapped inside a box near the Fallen Warrior. When Connor examined the box the ghost shook the box wanting to be let out. Connor destroyed the box finding only curative Mushrooms.
Behind the scenesEdit
This was added in as an easter egg.
Its a reference to novelty executive desk toy with a crate or box that shakes and yells "Let me outta here". The voice itself is taken from one of these desk toys.
