GOATSE

GOATSE is a series of videos/shorts done by Gerg where he takes a house on Gerg World and transforms it.
The acronym GOATSE stands for Gerg's Official Accommodation Transformation Specialty Emporium. 
==First Attempt==
Gerg's first attempt at GOATSE were when he still created shorts content, and included the videos:
*Upgrading YOUR Builds! (short)
*Minecraft Real Estate goes HARD (short)
==Second Attempt==
Gerg attempted GOATSE for a second time after 8 months, as Gerg World players wanted him to do another video on the server (which had diminishing player counts due to the lack of new players). 
Among other things he created a Discord channel in his server called #goatse where people could submit builds on Gerg World with coordinates and a screenshot, and he picked out the builds to "upgrade" based off of that.
It is known that Gerg is planning on making a new GOATSE video, as he announced a second one.
