When the gibbons spotted the peanuts in a plastic water bottle in their pen, it wasn’t long before they began to battle for the snacks.

The two gibbons reside at the Endangered Primate Rescue Centre in Vietnam where they are treated to different toys every week. One week there were given a plastic bottle filled with peanuts – making snack time a little bit of a task! Credit: Polish Dr Dolittle via Storyful
