I finally tracked down a bottle of Revlon Whimsical (dupe of Deborah Lippmann's Glitter in The Air) at Kmart. I know some of you have found it, and others are still looking for it. If you happen to still be looking, here is what the display looks like. It was large and on the end cap. Sometimes I find it easier to find something if I know what I'm looking for. So I hope this helps those who are still on the hunt for this polish.

Here are the polishes I purchased from that display. There was no resiting these sparkly beauties.
Left to Right: Popular, Scandalous, Stunning, Radiant and Whimsical.
Now, on to some random thoughts I have about Whimsical. Please keep in mind for now I have not used this polish yet. I don't particularly like this color at all. It's too light for me, and I avoided purchasing it for that. I do not buy polishes just because of the 'hype'.
I did have a change of heart recently. I saw a lovely swatch of it over a dark pink polish, and thought it was beautiful. I decided after that I needed it in my collection.
Hope if you are still looking for Whimsical that you do find it soon.
