Watchtower

The Watchtower was a gigantic tower built by Furternator and CephaloGOD in the Slum. It was first built up to a relatively high altitude but was later built up to max hight by Furternator and Haxor (using commands) posthumously.

In Episode Three (bonus clip), Furternator pushes Haxor off the tower, assuming he would land in a pond. However, Haxor misses the pond and takes fatal fall damage. However, Toulou decided this didn't count as an actual death and Haxor was brought back.
