The Earth Driller is a Ninja vehicle built by Dr. Julien and Nya with Cole in mind. It is a large black and gold vehicle resembling a race car with a sealed cockpit and a large golden 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.
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, the set is called "Cole's Earth Driller".
