Zuru Robo Alive slithering snake robotic toy in green, used but in very good pre-owned condition and tested to be in working order. Requires 2 AAA batteries, which are not included. Press the button at the base of the head (on the back) to remove the battery compartment (head). Unscrew the battery housing to insert the batteries. The on/off switch is located on the left underside of the head. Great for collectors or as a fun interactive toy that moves and slithers when powered.
