This portable sidewalk sign moves, waves and smiles. The gorilla robot stands 6 feet, 6 inches tall and the left arm waves while the torso moves left to right. The adult-size gorilla suit is made with quality latex and fur, available in pink and black, and it’s made with outdoor use in mind. Gorilla plugs into any 110 outlet. Package includes a 21-inch by 36-inch changeable letter sign with a set of 4-inch letters.
