A hippo who stopped eating is now happily munching away again thanks to a to a glove puppet. Chico, who is a pygmy hippo, worried keepers when he went off his food. After trying everything to get him to eat, they had a go with Gloria — a hippo glove puppet based on a character in the Madagascar film. The zoo said they were surprised when it worked — now everyone who feeds Chico has to use the glove puppet. Pygmy hippos like Chico need to eat quite a lot of food every day to stay well. When they live in the wild they can spend around six hours a day just eating.
