I don’t remember much of this movie but what I do remember it involved -
The main character is going through his family’s house.
The talking corpse of his grandfather, dressed like cowboy/miner
They find some crystal ball or orb type thing
The main villain is a skeleton like cowboy all in black
I think some weird little worm pet they find?, that is after the orb and the grandfather
I also wanna say there is a door that leads to a cave or something but I may not be remembering this part right

I think i would see it on USA or SciFi years ago on Saturday mornings…

Anyone have any clue what movie I am talking about here
