I visited the Happy Hollow Park & Zoo last weekend. The picture you see is a donkey in the "Animal Contact" area. He was one of many animals where visitors can buy food for 25 cents (0.17 Euro) to feed them.
In the photo, this donkey looks sad and hungry and appears to hypnotize you into buying him food from the dispenser. But, don't be fooled, he was the first animal into the Animal Contact area and received the most attention.
