Bust-a-Where?

I've been all over town looking for Bust-a-Move DS for Nicole for her stocking. The only problem is, I don't think it really exists.

I've been to Wal-Mart, Toys 'R Us and both Gamestop and EBGames.

I even spoke to the guy at EBGames and he said he was also unable to find it. The flyer he picked up for Toys 'R Us said they had it but they didn't.

I'm easily able to find it online, but where are the units in the stores?
