The peek-a-boo goat. From the description of the video:
This little miniature goat is a sweet addition to our little petting zoo, She was so shy when we first got her I thought she would never interact. That is when I thought up “peek a goat.” She loves this game and now is very social. I just hide behind her little house in her pen and she gets so curious she peeks around the sides and over the top at me. She now will follow us anywhere we go in the yard, and loves to be petted.
