"Let me do something...." She approaches Star slowly, and murmurs in what she thinks of as her 'horse voice': "Hey...Dagmar wants to check whether you've got anything stuck in your hooves. She's not trying to do anything to hurt you, but it might be a little uncomfortable. Why don't you lean against me, and I can help steady you if you get startled?" She steps a bit closer, so Star can rest her head over Sylvi's shoulder if she is agreeable.
