This Advent Calendar builds into a nice selection of figures, vehicles, bits and pieces, and even a little police station, with furniture and a safe. I liked that there was that variety, rather than just figures or just tiny mini-sets. The cardboard box folds open to reveal a backdrop of 2011 City Lego sets, and a flat scene of a snow covered pond, with greenery, footprints, ski tracks and broken ice.

• two police officers and a dog
• two criminals
• an ice fisherman (nice green hooded parka, with printed fur)
• Santa with backpack
• a small police car (built in three stages on a small black car chassis)
• a police station, (built in four stages)
• two snowmobiles (one has a trailer)
• a Christmas tree with presents (including a skateboard and helmet)
• a snowball catapult
• a fireplace with clear orange 1 x 1 cheese wedges for fire

The figures all have printed torsos, including a green jacket and a grey jacket over prison stripes. The police station is four 2 x 6 wall or door sections built up and joined together. It is over 60 pieces, including brown 'timber' style bricks, blue 1 x 2 peg and 1 x 2 hole bricks, a blue 1 x 6 arch over an empty doorway, and different sized windows/bars. White slopes at the top depict a snow covered roof, but there is no proper roof or back (which makes it easier for little hands to play with it). There is a bed, a forensics desk and a safe with gold bars!

There are lots of nice spares too: there is an extra white 2 x 1 tile with Police printed on it, spare 1 x 1 brown bricks, two extra skis, an axe, a radio, handcuffs, 1 x 1 tiles and 1 x 1 round clear plates.

Because the Santa figure has a beard piece and a backpack, I did find that I had to press reasonably hard to get the head to attach. Very small kids might need adult help with that.

The box art doesn't give away all the contents of the Calendar, although there is a depiction of parts on the side. So, this set should surprise kids with its contents - this set has a really good assortment of gifts inside!
