Like other games in the New Play Control! series, Chibi Robo's controls are revamped.

The next game to receive the New Play Control! treatment in Japan is Chibi Robo. The biggest change for the Wii release is the addition of point-and-click controls to make the robot move, replacing the analog stick control in the GameCube version. Motion controls have also been added to the in-game chores, such as sliding the Wii Remote back and forth to clean paw prints with a toothbrush.
An interesting side note regarding this control scheme change is that the game was originally supposed to be a point-and-click adventure before Skip Co. began co-developing the title with Nintendo.
New Play Control! Chibi Robo will be released in Japan on June 11. There is currently no US release date.
