My Hidden Things (EP)

In Ophelia chapter 3 you will see a girl in a hot air balloon. There are sandbags on the balloon, click and drag the heart locket so only the smaller heart comes out, place that in the sandbags and the achievement should pop. Other items to put inside the sandbags include, the handcuff that's buried under some stuff, and if you click on the turtle's eye it will become a ring, place those 3 items in the bags to finish the level.
