Chibi Robo Park Patrol review at Gamespy.

"Despite being a fun and endlessly charming adventure game, the original Chibi-Robo for GameCube was not one of that system's biggest hits. Perhaps that's why this portable sequel is a retailer exclusive (it's only available at Wal-Mart). Don't let its limited availability scare you away, though. Chibi-Robo: Park Patrol is an addictive title that's a bit deeper than you might imagine."
