Baby can take the wheel with this key set. A black-and-white-striped “key chain” holds the three keys in tonal colors — colors close to each other on the color wheel — to help improve baby’s visual acuity. The keys offer raised ridges, bumpy dots and key-shaped indentations to encourage tactile exploration. A variety of dynamic car sounds can be heard when baby pushes the three colored buttons on the key chain. The keys also make clacking sounds when shaken. "This toy offers visual, auditory and tactile stimulation and encourages baby to engage in pretend play," Peggy Barrett, PR consultant at Barrett Marketing Communications, told TDmonthly. Launch date: July 2009.
