"Seven seconds have passed... ROAD ROLLER!!!" -High DIO Part 3 (DlO, ディオ).
The Bulldozer was a tractor equipped with a substantial metal plate (known as a blade) used to push large quantities of soil, sand, rubble, stone or other such material during construction or conversion work and typically equipped at the rear with a claw-like device (known as a ripper) to loosen densely compacted materials. It is usually a crawler (continuous tracked) tractor. Inside the window, the ex-owner of the game, TheGuestToBlame could be seen operating it.
The Bulldozer has a mostly yellow color-scheme and is shaped like a truck. The wheels, however, look like Continuous track, also known as the wheels of Tanks.
The Bulldozer in-game is also seen to be pushing dirt to create a path from the tunnel behind it to where it is now.
There was also a tunnel/cave behind the Bulldozer, where the Enhanced Holodummy used to reside. On the right side, Bob can be seen fishing in the Grassy Bay. A few buildings to the right of the Bulldozer is where Tom's Shack is located.
- TheGuestToBlame used to carry his Pot Platinum with him while inside the bulldozer, however, it was deleted after the "New Map" update.
- You can use King Crimson's Erasure Shift, Made In Heaven's Light Speed Teleport, Shadow The World's Time-stop Teleport, etc. to get inside the Bulldozer.
- The Bulldozer seems to be cleaning the grass and making a street. This could be hinting that maps aren't different places, rather the same area renovated over and over again for many times.
