The Doctor's Key is a key item in Animal Hospital — it's not a weapon or consumable, but an object used during specific NPC interactions. It appears during certain shift events and is tied to the Barney NPC storyline.

How to Get the Doctor's Key

The Doctor's Key is obtained through interactions with Barney, a special NPC who occasionally appears at the hospital:

1. Barney visits the hospital during certain shifts
2. He may give you the Doctor's Key as part of an interaction
3. The key appears in your inventory once obtained
4. It persists for the duration of the shift

Barney is not guaranteed to appear every shift — he shows up based on random events or shift progression.
