After their shower, Thomas placed Rocky on a playstand. What happened next was very strange, as Rocky and Max rarely interact. Max flew over and then they started fighting. Of course, as soon as I came over with the camera, they both acted innocent.
Perhaps Max was upset that she wasn't invited to shower with Thomas? (I thought he and Rocky needed some alone-time, though then I showed up and started taping).
You can see in this video that she had her foot up, ready to step up. After I separated them, they were fine and neither one bothered the other for the rest of the day.
