Trees have been planted around the "outside" of Dumbo 2. In time, this will provide a barrier to the Tomorrowland Speedway.
Work continues on the Seven Dwarfs Mine Coaster. You can see more of a themed hill going into place. Work continues as well on Under the Sea's caves.
One of the construction walls near the front of the land has been replaced by a more temporary wall.
In the back of the land, there's a building under construction beyond Casey Jr. Splash 'n' Soak. Will it have something to do with Pete's Silly Sideshow? Or Humphrey somehow? The other characters promised for this land are already accounted for.
Around the backside of the restrooms is a series of trunks and bags, there to provide some theming. They aren't new, but they used to be unlabeled. Now there are mentions of several Disney characters.
Finally, two Hidden Mickeys to show you. The one stamped into the ground has been there since opening day of the land, but the one made up of stones, close to the exit of the trains, is more recent I think. It may not be "official" either.
