Now that we've got the creepier Easter eggs out of the way, here's a fun one that's a real precious (ahem) find.
Referencing The Lord of the Rings, this Red Dead Redemption Hobbit-hole can be found in Ambarino, northeast of Fort Wallace.
Basically, a hole dug in the hillside with a front door and maybe a window or two, this structure would make even Bilbo proud.
unfortunately, you can't enter the house through the door or any other opening. Clearly, Rockstar just dropped this Easter egg in RDR 2 for fun.
