This is 72nd episode of Monkey Go Happy series called the Chocolate. What you do is to look everywhere and underneath everything to collect chocolate buttons and candies into the bag. Of course, while doing that, at the same time you are supposed to find all of 10 mini monkeys, which is now the usual side-task in all MGH games. The funny guy in a hat on the first stage specifically request 35 chocolate button, so this is how many you must collect.
