Moves like the real thing! Looks like the Eastern Diamondback rattlesnake--the largest, most dangerous rattlesnake native to the U.S. Let this one "loose" in your house and see who freaks out! Moves left, right and in a "S" shaped pattern, just like a snake does. Snake uses 4 AAA batteries, not included. Remote uses a 9-volt battery, included. Approx. 29"x 2.5"x 2.5". WARNING: Choking Hazard - small parts. Not for children under 3 yrs.
