I saw a story where a simmer tried to marry the Grim Reaper and ended up corrupting the game files. Yikes! Don’t do that!
Here’s my completely safe regular sim version of Grimmy for you to play with, ACR with, whatever floats your boat with.
I have seen an older version of a playable Grim, but it had some issue with the scalp, I think? This one does not. S/he’s looking good with Bink13y and Zuperblah invisible skin, eyes, hair, and face and my unhidden, recategorized for all categories, no-lei grim robes. Shower-safe. S/he’s alive and walking the hood, but could be made into a ghost if you prefer.
