SpaceX Starlink mission filmed something odd, in addition to the mouse that ran across the nozzle of the rocket. Looks like a frisbee, and the mouse actually looked like a mouse but how could it be?

The direct link for the mission is here: https://www.youtube.com/watch?v=4_ePBpwMhns

The anomaly takes place at the 20:30 mark; this is the link that takes you to about that timestamp:

Watching the right screen, starting at 19:00, looks exactly like a mouse runs across the middle part from top to bottom and stays there.
