Pandas move while they're eating or hide their faces

Was just playing around with the pandas, so I fed them...But then, they were moving while they were eating, I'm not really sure if this is a problem but just incase. (They were eating bamboos.)

Reproduce

1. Summon a worried panda with a command
2. Trying to get close and scare it away
3. Set the weather to thunder
