Watt
Watts are electrical charges that all Chibi-Robos must depend on.
Purpose
Watts are a Chibi-Robo's life energy. It powers them up to keep them running and acting so they can continue performing. Since Chibi-Robos are autonomous robots, they slowly lose watts with each action their perform, including standing still. Should Chibi-Robo be hurt in either way, they will also lose watts as well.
Watts are also used as currency in Chibi-Robo!: Park Patrol.
Charging watts
To recharge watts, the player can plug their Chibi-Robo's Chibi Plug into an Outlet to recharge their electrical energy.
In Chibi-Robo! Photo Finder, the only outlet that the player can plug into is in the Curator's Office. Not only that this is the only method of recharging Chibi-Robo, there are multiple batteries scattered throughout while exploring. If Chibi-Robo picks up a battery, it recharges them to 100% watts.
Running out of watts
In Chibi-Robo! and Chibi-Robo! Photo Finder, should the player run out of watts, Chibi-Robo will power down and result in a "Game Over." The player would be returned to their Chibi-House or home for a emergency recharge by Telly Vision or Telly.
If the player runs out of watts during a job in Chibi-Robo! Photo Finder, Chibi-Robo will lose all progress made within the job and will earn zero Happy Points.
