Two new additions to the Magic Kingdom’s Fantasyland Expansion were announced today on the official page of the project, as well as some details on the other attractions coming as part of New Fantasyland:

Beyond the Horizon — New Expansions

“We keep moving forward, opening new doors, and doing new things, because we’re curious and curiosity keeps leading us down new paths.” —Walt Disney

The Fantasyland Expansion
Princesses, Dwarfs, Beauties and Beasts have all been working past midnight to unveil the grandest expansion of Magic Kingdom theme park ever! Scheduled to begin opening in 2012, here is a glimpse of the future of Fantasyland:

Storybook Circus
The sound of the calliope will lead you to the brand new carousels of airborne pachyderms on Dumbo the Flying Elephant—now with 2 Dumbos! Before taking to the skies on this Fantasyland favorite, experience an array of fun-filled family games and interactive wonders for kids of all ages inside the Big Top.

Barnstormer
Hosted by the Great Goofini, this daredevil roller coaster, which twists and turns high above the Storybook Circus grounds, is getting a bright new look.

Casey Jr. Roundhouse
Adjacent to the Fantasyland Train Station is the Casey Jr. Roundhouse, a circus-themed immersive water play area that’s fun for the little ones. They’ll splish and splash as Casey Jr. billows off cool steam and water squirts from playful monkeys, elephants and camels.

Under the Sea: Journey of The Little Mermaid
Make a splash with Ariel as you take a voyage in a clamshell into a world of imagination under the sea. This attraction features her friends Sebastian and King Triton and, of course, music from the Walt Disney Pictures film.

Scuttle’s Scavenger Hunt
While approaching Ariel’s Grotto to meet The Little Mermaid, join Scuttle for this fun, interactive game! Search the seaside entrance way to find the seagull’s treasures from the Human World, like a dinglehopper or a bulbous snarfblatt. Scuttle will be on hand to help with the hunt.

Enchanted Tales with Belle
In Maurice’s workshop, a magical mirror is your doorway to a captivating storytelling experience. Transport to the Beast’s library to meet Belle and Lumiere, and share in a lively, interactive re-telling of the “tale as old as time.”

Be Our Guest Restaurant
Experience the elegant ballroom, gallery and mysterious West Wing of the Beast’s castle. With seating for 550, this magnificent dining hall will offer great quick-service meals by day and full table-service dining in the evening. Nearby in Belle’s Village, discover the rousing Gaston’s Tavern and Bonjour!

Princess Fairytale Hall
Greet Aurora, Cinderella and Tiana and in their new home, an elegant royal court fit for every princess.

The Seven Dwarfs’ Mine Train
Heigh-ho, heigh-ho, off to work you go! Take a rollicking, musical ride through the Seven Dwarfs mine—where a million diamonds shine. This roller coaster features a first-of-its-kind train that responds to every twist and turn of the track . The journey will be accompanied by music from Walt Disney’s animated classic, Snow White and the Seven Dwarfs.

The Casey Jr. Roundhouse is not a big surprise, as we can actually see it in some early concept art (pictured below). On the other hand, “Scuttle’s Scavenger Hunt” is something completely new to us. We expect this to be very similar to the Kim Possible World Showcase Adventure at Epcot. Stay tuned to WDW News Today as more information on the Fantasyland Expansion becomes available.

UPDATE:

Here is the concept art for the Casey Jr. Roundhouse released in the large overall concept back in January:

Also, multiple reports have confirmed that some early testing was conducted for Scuttle’s Scavenger Hunt inside the queue of The Seas with Nemo and Friends about a month ago.
