I'm looking for a specific type of mod that adds Herobrine back to the game, and that encapsulates all the old feelings associated with him, complete with his specific behaviours, where the mod has all his classic tendencies of building pyramids, scalping trees, placement of redstone torches, 2x2 tunnels, and to where Herobrine himself appears in the world, watching the player as always.
Preferably some of the previously described actions should be spawned in with the world, as well as gradually spawning in over time, to where his structures and spawnrate of himself to be too overdone, what he does should subtle enough that you still notice it, still know he's there, but not to where new structures spawn so rapidly.
It shouldn't be like the other mods I've seen where it blatantly shows his presence, I want a subtle mod, not one that shows a message in chat that "Herobrine has joined the World" or spawns 100 pyramids within 700 blocks of spawn and litters the mountainside with 2x2 tunnels and redstone torches.
Not sure if this covers 'all' the things Herobrine is known for but there is a few Herobrine mods out there. This one I covered a while ago (not a skin or so type mod but acts as more so a boss, more has been added to it over time since I last covered it though and other Youtubers can also showcase that more than I can)
