RBTA Concern?

[ponokareefer]

Hello everyone,

I was wondering if my RBTA's activities should be a concern to me or not. What is happening is it is shrinking down pretty small for about an hour a day with it's mouth open. Nothing ever comes out, and it eats 3 times a week, half a silverside. It stays in the exact same spot everyday, fully expanding otherwise, with a cinnamon clown playing in it.
