Alone in a Cave...
Head inside, nothing bad ever happens in churches.
Oh, it's a burial vault/tomb. Not a church.
Well, then don't head inside. All kinds of bad things happen in tombs.
Get your new dog friend to dig up both graves. Disturbing the dead is sure to bring good luck!
Bury one of the zombie corpses. Maybe it's like a reverse-Pet Sematary-type area, and they will come back to life as normal people.
Explore the tomb! Send rat in first since she's got a hardhat
WE NEED THE MUSIC!
