I think a land themed to the Galapagos islands would be a perfect fit of Animal Kingdom. I've had this idea for a while, and I thought i would share it. The land would consist of 3 rides, 2 E-tickets and one small children's ride.
The first attraction would be a fast paced roller coaster themed to the various lave tubes of the Galapagos. This attraction would dip and dive in and out of lava tunnels offering a view of the inside of the tunnels as well as a view of the landscape above. The ride would end escaping from the tunnels due to incoming lava. The ride vehicles would appear as mine carts some what similar to the Indiana Jones attraction in Disneyland Paris.
