Hey Ya! The second mod is dedicated to a dog that always came to the station and waited for its owner after work. But one day he never returned, because on the way home he became ill and died. I think everyone knows this story. Of course it's Hachiko. The dog came to that place until his death, where a monument to her is erected to this day (Shibuya station, Tokyo). Here is a mini Easter egg. You can find her at the station in San Fierro. Why is she a ghost in the game? Because, in my understanding, the ghost in the game is the perpetuated memory of a person or, in this case, an animal. P.S. Knowing that a similar question will arise, I put the usual model (not a ghost) and the script without its disappearance also in the archive.
Differences: Ghost. Appears at night, but not always. There is a time limit. Disappears when you try to get close. Not a ghost. Appears at any time. Once since loading the save.
