Deep Jungle

Sora enters Deep Jungle alone and at the Tree House, where he meets up with Tarzan and Sabor. Jumping down from the netting below the house sends Sora into the Tunnel, where he can either use the save point, access the Treetop and Climbing Trees to head back to the Tree House, or jump into the log and begin the Tree Surfing mini-game.
Tree surfing takes the party to the Camp, where at the Tent within the party can meet with Jane and use the save point within. The east exit from the camp by the stove and experiment table leads to the Hippos' Lagoon, which can only be traversed with swimming, good timing, and well-aimed jumps. Heading across the Lagoon takes the party to two areas, Vines and Vines 2, which are home to the Vine Swinging mini-game. Vines 2 in turn leads back to the Climbing Trees.
Heading out the north entrance of the Camp by the clothesline takes the group to the Bamboo Thicket, and continuing through the Thicket leads to the Cliff. After the last battle, Sora and his party gain access to the Waterfall Cavern. Sora and party are required to climb up the cavern. At the top of the cavern is an entrance to the Cavern of Hearts, the supposed heart of Deep Jungle, where the sound of the waterfalls echo and where the Keyhole is sealed.
Notice that in the Climbing Trees area of this world, there is a different means of moving through out the area called Vine Swinging. This is simply the process of jumping from one vine to the other to get from platform to platform.
