Age 6. Optimus Prime Voice Changer
Even if your child isn't under the grip of Transformer-mania, he'll love Hasbro's Optimus Prime Voice Changer helmet. It will morph his voice to sound robotic, or simply play one of five Autobot catch phrases like "The Decepticons must be stopped!" The helmet adjusts to fit adult head sizes — handy for the moments when nostalgic Gen-X parents want to share. Recommended for ages 5 and up; $29.99.
