|“I love having this baby again! Aha! Best present ever!”|
|— Cole, referring to the Earth Driller in "The Weekend Drill"|
The Earth Driller is a Ninja vehicle built by Dr. Julien and Nya for Cole. It is a large black and gold vehicle resembling a race car with a sealed cockpit and a large golden-colored drill on the front.
When the Ninja returned with the Stone Army hot in pursuit, Nya and Dr. Julien presented the Earth Driller to them. The Ninja used the vehicle to avoid the Stone Warriors by moving underground. They arrived at the mountain leading up to the Temple, but it was unable to traverse, so they decided to climb up the mountain using the Fire Mech.
When Wu showed Misako the murals in the Monastery, Wu wondered why one of the monks painted the Earth Driller.
In a flashback, Cole was enjoying a ride in the Earth Driller when he got a message from Warden Noble that there was trouble in Kryptarium. When he arrived he saw that the Giant Stone Warrior escaped its cell and tried to contain it with the Driller. In the process, Killow and Ultra Violet's cell door broke down. Killow attacked Cole, but he put them in their cells. Once he stood victorious, everyone booed at him for destroying the prison.
Back in the present, Wu decided to keep the painting there, stating that it can't do any harm.
Cole, Zane, and P.I.X.A.L. used the Earth Driller to try and get to the Ninjago City Docks, but got stuck in traffic. Cole attempted to drill through the road, but Zane and P.I.X.A.L. said that people wouldn't like the freeway getting destroyed again. The Ninja eventually got out of the Earth Driller and ran to the docks, abandoning the vehicle in the city, although Cole closed the cockpit. The city was then conquered by the Oni.
Cole used it to get back to the Monastery of Spinjitzu. Later, The Omega threw it over the edge of the of the mountain and it is unknown what happened to it after that.
The Earth Driller's large tires allow it to go across all kinds of terrain. Its drill allows it to tunnel through the ground with ease, and can also be used as a weapon.
It can carry all five Ninja in its cockpit, and the compacted Fire Mech can be stored in the back.
- The Earth Driller is a playable vehicle in LEGO Worlds.
- Just like the Roto Jet, although it was never specifically Cole's vehicle (until Season 10) when the set was called "Cole's Earth Driller."
- The vehicle in Season 2 could seat up to seven people. However, the original set could only seat one minifigure, and the Legacy remake can only seat two.
