In the video, we see an octopus in a tank. The octopus is moving its tentacles around and appears to be playing with a ball. The tank is filled with water, and there are rocks and coral visible in the background. The octopus is a light brown color, and its tentacles are long and slender. The ball is red and appears to be attached to a string. The octopus seems to be enjoying itself as it moves around the tank, exploring its surroundings.
