aventuring ring

Did she or didn’t she?

I’m watching Horrificator (for a crack post, why else?) and this happened.

She points at him, there’s a ding that I’m not even sure I heard and he reacts with “you did it again!!”

They act like she rung his bell, but SHE NEVER TOUCHED IT.  Did I miss something or did the animators?

I need to know for reasons ¬、¬
