4x18 - MegaMan NT Warrior

While searching for Lan, Maylu and Chaud meet Moliarty and Press, NetOps of GroundMan and DustMan respectively. They're given a job by the Beyondard alternate of Ms. Millionaire to excavate through a rocky mountain for a precious item on the other side. Maylu and Chaud offer to help in the difficult excavation. (This is the only episode in the entire franchise where neither Lan nor MegaMan make an appearance.)
