It's something more ghoulish than a burning ghost...
Something more revolting than a mummy...
It's... A Flaming Ghost Mummy
-dramatic music-
Not hard to make, but fun to have around
Normal sims with haunted houses would say
"Hey... Sooo I heard you've got a haunting, what is it?"
"Oh nothing...just a FLAMING GHOST MUMMY!!!"
"Holy Simoly! You've got a flaming ghost mummy? All I got are some child ghosts and it's boring compared to your wacky haunting"
So start making your own ghost mummies!
And be the coolest, haunted sim lot in the entire town
