The Mop (モップ Moppu?) is Crono's weakest weapon, basically a joke weapon, in Chrono Trigger.
In battle/in-game, its sprite still visually resembles a katana, awkwardly enough. This weapon is colored tan while unlike all of Crono's other weapons, has no unique slashing trail of any sort.
Obtain
The mop is obtained by charming a Nu.
Effects
It has an attack power of 1, despite it being a wooden weapon akin to his Wooden Sword.
Dimensional Adventure Numa Monjar
The Nu and Mamo believed they could recruit Fiends into their gang by offering free mops. They were proven wrong and ended up playing the Drinking Contest Game in Leene Square to win a Golden Shovel and offer that as incentive instead.
