"Ready, set, go!" The spider tumbler moves forward and backward under your control. The extra wheel allows it to turn sideways. Rotates and performs full spins. The techno car's body and spider-like arms extend and retract with transformer-like action. Multicolored LED lights on each tire, especially effective in the dark, add strobe lighting to your very own stunt show. Full-function wireless remote control has 2 frequencies available for racing against another stunt car. Requires 4 "AA" batteries.
