Not only is it nicely challenging, it's also rather cute. Adorable, in fact. Like the "find 10 gnomes" one. :-) I strongly recommend folks try to tough it out on this one before looking for walkthroughs & whatnots - it's actually fairly doable with a little bit of thought & observation, and is rather satisfying to solve entirely on your own. :-) (I know - I've "cheated" (aka "walkthrough") on any number of these things - I didn't on this one, and liked it much, much more).
