# Room 71: Cave Entrance

## High-Level Summary

Room 71 is the cave entrance area in the Troll Cave region. It serves as a transitional room connecting the upper area (room 72) and the south entrance (room 74). The room features a dark cave environment with a waterfall visible outside, a pile of bones that can be collected, and dynamic lighting effects based on whether the player has the lantern. This room is notable for its darkness mechanic - without the lantern, the cave is extremely dark, and with the lantern, visibility is still limited.

## Look Description

"This is the darkest cave you've ever seen!" (varies based on lantern possession)

- Different look descriptions are shown based on lantern possession

### Bone Collection

The bone (inventory item 23) can be collected when:
1. The bone is in the room (owner is 71)
2. Player is within 15 pixels of the bone prop (newProp_2)
3. When collected: bone is added to inventory, getDown script plays animation, global182 is set to 1, score increases by 2
