One tentacle is about 15 inches (35/40 centimeters) long, so with spread tentacles the cyber octopus is 30-35 inches (80cm) wide. The head is about 8 inches (20cm) long and 4 inches (10cm) wide. There are 3 LEDs powered with a 9V battery. Two red ones for the eye and one blue for the rear engine. There’s a switch to light the LEDs. Tentacles are held together with a 5mm elastic cord, you can pose them as you wish, but they are not strong enough to hold the octopus on a pole for example.
