Save the Chimps Sanctuary occasionally puts in the enclosures / islands that are home to diverse groups of chimpanzees boxes or envelopes with various items such as dried fruit, chocolates, jellies and other treats that chimpanzees like.
In this photo, we see the joy of Melody when she “found” an Easter egg in a box apparently abandoned on their island.
