I somehow missed these...
Never saw them at the store; yes, they're basically blue Hostess Sno-Balls. Blue-balls, if you will. I've seen the pink ones, the green St Patrick's Day version, yellow for easter and orange for Halloween. But never blue. Now if they'd do lavender for Pride Day we'd have the whole rainbow!
ETA: damn, they also had blue-frosted cupcakes! (Turns out both were only available at Wal-Mart. Bastards!)
