These items are not strictly required for progression but are invaluable for navigating the house and avoiding the Neighbor:

- Boxes: Can be stacked to reach high places or used as temporary cover. They are abundant throughout the house.
- Trash Cans: Similar to boxes, they can be stacked or used to create noise distractions when thrown.
- Rocks/Bricks: Excellent for breaking windows, activating distant switches, or creating noise to distract the Neighbor. They are throwable items.
- Water Bucket: Can extinguish fires (e.g., to access a room blocked by flames) or be used to short-circuit electrical panels.
- Glue: Can be used to temporarily stick objects together, or to stick the Neighbor's feet to the floor if he steps on it (though this is rare and difficult to achieve).
- Umbrella: Can be used to slow your descent from high places, acting as a makeshift parachute. Also useful for deflecting certain projectiles or interacting with distant objects.
- Radio: When turned on, it emits loud music, serving as a powerful distraction to lure the Neighbor away from your intended path.
- Bear Trap: While primarily used by the Neighbor, you can pick up and relocate disarmed bear traps to set your own traps for him, temporarily stunning him.
Experiment with these items to find creative solutions to problems and to outsmart the Neighbor's adaptive AI. Combining items can often lead to unexpected and effective strategies.
