Bratz Babyz is based on the toy line of dolls of the same name. The game is set in a mall where the Bratz Babyz need to escape their daycare and rescue Snappy from the clutches of the evil Duane. This is done by playing numerous mini-games where 'Blingz' are earned as a currency. The mini-games can be selected right away from a central area.

The names of the included mini-games are Balloonatics, Castle Mazenstein, ExScream Makeover, Fashion Skate, Fountain of Youths, Hop and Seek, Karaoke Time, Ring for Blingz, Snack Attack, Snappy's Wild Ride, Sweet Necklace Treat, Top Trumps, and Wash a Pooch.
