Chibi-Robo: Park Patrol Cheats - Nintendo DS
Hints
Pink Kuros
When you have beaten the game (this is to say kill the smoke boss) the kuros will turn into pink kuros and they will continue to invade your park sometimes but instead of changing a flower into a black flower, they will change it into a rainbow one.
Unlockables
Beat the game once to unlock unfinite energy and park editors.
