Look for precious lava stones with Steele the StegosaurusTM and Sigma the TherizinosaurusTM from the Switch & Go Dinos Lava ForceTM by VTech! Each dino is a 2-in-1 toy that transforms from a dinosaur into a fast vehicle in a few easy steps. They'll recognize the included CyberRiderTM or GeoRiderTM characters and will have unique conversations with them. Steele and Sigma each have an LED that turns a different color based on whether he or his rider is talking. They also play realistic sound effects and interesting dino facts, too! Included in this package are One CyberRiderTM, One GeoRiderTM, saw and drill play pieces and two suits of armor. Each dino requires an AAA battery (batteries included for demo purposes only; new batteries recommended for regular use); intended for ages 3 to 8 years.
