Thank God for mute!
The first "hidden object" I searched for was the mute button. Because that piano was driving me nuts after just 2-3 repeats (so within the first minute of playing).
Other than that... I don't really see what it has to do with the Shire, other than the background. Sorry, man, but you could as well have stuffed in a Terminator background and called it Hidden Objects - Terminator (or Governor, whatever you like most).
