Mine's ice burr-ista (from the 28 Jan update)!
Just done decorating for winter/ Christmas and was beating myself up for not having bought more from that update.
We've had quite some bad updates/ designs in 2015 but still I'd like to take this opportunity to thank S8 for this great design!
And also PepperWoo (and others) for always posting photos for other players.
P.S. LTOs (e.g. Valentine sale/ fall sales) do not count!
