Look! Up in the air - it's a bottle, a pacifier, a diaper? No, it's Bratz Super Babyz in an out-of-this-world new movie. When the Babyz' sitter, Gran, finds a "matter exchanger" dropped off by aliens from outer space, she accidentally mistakes it as a remote control. She pushes the button and "zap!" The Babyz are transformed into super babyz. Cloe becomes "Sirena," Yasmin, the "Speedy Princess," Jade is now "Glue Girl," and Sash becomes "Smart-asha!" The Babyz decide to use their powers for good, but face a challenge bigger than they expected. The aliens return to find their matter exchanger, and the Babyz must square off without their new powers. By overcoming their shortcomings and by working as a team, the Babyz discover they already had powers more powerful faster than a speeding stroller and more powerful than an exta-absobent diaper!
