Each happiness point contributes about half a percent to a frog's happiness. A maximum of seven scenery items can be added to each habitat, including the nursery.
Scenery can be shifted to other habitats, sold, or gifted by holding the item with your finger until a menu pops up on the lower end of your screen. Scenery can be moved around within the habitat simply by dragging it. Two of each item level of scenery are available in the Supply Shop for purchasing every day and the items change daily.
If a habitat features 8 frogs, 186 points of happiness by scenery are required for the frogs to reach 100% happiness. The most economic way to achieve this goal is to buy five items of level 7 and two level 6 items since cost grows quicker than happiness value of scenery goods.
