When at the waterfall, we should not see the shop. We should not have the user able to interact with the shop either.
By clicking navigation on the image, a sign showing 'Goto the Shop of Curiosity' then it will take you to a different animation of the shop. Your collection is shown, however throwing coins should be disabled as you are not at the waterfall screen anymore.
On the waterfall itself, the tablets will be shown, but will be interactive when clicked and will show the results over-top the waterfall. Include an X to close the pop-up.
