I got this on my game of cursed in PJ
This is not the collar you give to the purple cyst !
It does not spawned at the same place neither with the same conditions and it trigger a voiceline from the zombie twin which is "I remember Fluffy, she was a good dog"
I got it by killing a Mimic with the Blundergatt while switching timelines (from past to future). I thought it was what triggered it but then I tried to replicate it and could not manage to get the item to drop.
I'm no longer in the game so I cannot try things.
Does anyone had the same item ? Any leads on it ?
