Shape shifting ball in sky, Black ball with legs flew on neighbors roof fast and ran across roof, Shape shifting saucer or saucers

On 8/3/21 At 4:45 am I started videoing something bright in the South sky that was rotating, changing colors size and shapes. I heard an aircraft from the West and I look and there was a flying saucer and a black ball with legs landed on my neighbors roof and ran until the tree blocked my vision. The saucer had went more South and was closer to the rotating thing. The black ball thing with legs appeared again and disappeared. The saucer turned and headed West. I have a video of all of this and screen shots.
