Invisible Cave Giant

Invisible Cave Giant in Red Dead Redemption 2
There is a special character in RDR2 that resembles the Big Foot Easter Egg from GTA V. However, this cave giant in RDR2 is invisible. People normally thinks that he is inside the cave, but as you can see from the videos below, going inside the cave reveals he is not really there when talking. Instead, the cave giant is invisible outside his cave.
