Adorable moment mischievous baby gorilla attempts to annoy his older brother

This is the adorable moment a mischievous baby gorilla attempts to annoy his older brother by throwing hay over him. The two gorillas who live at Givskud Zoo, in Vejle, Denmark are seen in their monkey enclosure entertaining themselves with the hay supplied by their keepers. In this sweet footage, the baby gorilla named Yeba, aged six, appears to be smiling as he picks up the straw and throws it in the air - nearly hitting his brother in the face. The older brother, who is a Silverback named Kipenzi, 16, appears to have a straight face as he puts his hands up gently to try and stop his younger brother annoying him.
