petting zoo in gevim

Gevim has a petting zoo too! With horses, rabbits, turtles, fox, birds, and wierd animals too such as these goats. I tried to help them and take off the yellow buttons they have in their ears, but they kept running away. They did not even want to eat what I tried to feed them...
What can they be afraid of, I can't be bigger then they are, or did I grow up so much already?
