This is a small christmas tunnel for the Norwegian youtuber "Addexio" and for his Advent Calendar.
Just a small improvement on the outside and inside of his tunnel on his channel.
Where to stand to get it in: Stand on the DARK BROWN SLAB (the first wood plank thing after you exit the tunnel) and it should be perfectly applied, I used the same seed as you, and everything so far is looking similair.
Version is 1.12.2.
Hope you like it!
