The Town That Disappeared - S2.E8

Naga sends his most powerful warrior, Bajarl, to destroy Genki and the others. Bajarl traps them in his jar, and only Holly and Mocchi escape. Holly then stumbles onto a ghost town that was wiped out by Bajarl. Holly reads the mayor's diary, realizing that the mayor rigged a huge rock formation above the town with explosives. She blows up the rock, trapping Bajarl and saving her friends.
