Pipe...

Pipe... is a paper note in the Fallout 76 update Wastelanders.

Location
The note can be found on a dead settler near the titular pipe in the Unusual Pipe random encounter.

Behind the scenes
This note and its related random encounter were created by level designer Zachary Wilson, who described it as "some nonsense [he] made at 8PM on a Wednesday at the end of the project when no one was looking," yet also called it his most successful contribution to gaming.
