The two items are the Dog Sled and the Winter Creek. The Dog Sled is like that you'd find running in the Iditarod - the "Great Sled Race" - that sees participants racing their dog teams through arctic conditions. The Winter Creek, then, represents once such arctic condition - a chilly little stream of water surrounded by snow-covered pine trees.
Both of these items look to be decorative only, as we can't see the Dog Sled actually being released as an animal item, or one with a function (although watching your avatar ride around on one would be cool, I must admit), but remember, there is no guarantee as to whether or not these items will officially launch in the game, so keep that in mind.
We'll be sure to let you know when and if these items are officially released in the game, so keep checking back!
