Vine Swinging (ターザンつたわたり, Tāzan Tsutawatari?, lit. "Tarzan Vine Swinging") is a mini-game located in Deep Jungle in which you have to swing quickly from vine to vine in several challenges which include time trials and falling vines. If you fall off, you will land in the Hippos' Lagoon below. The game is able to be played after Sora meets Kerchak. The goal is to reach a certain tree, and that advances the story.
From the Hippo's Lagoon, climb the vine nearest the exit to the Camp area. Sora should auto-target the yellow flower located near the save point. Now move behind the flower so that the camera faces the vines. Examine the flower and when it blooms, accept a time trial challenge.
When you acquire the shared abilities Glide and Superglide, return here and try the Vine Swinging mini-game again to dramatically improve your times. If Sora sometimes doesn't grab a vine with enough forward momentum to reach the next one, you can use these abilities to enable you to skip a couple vines if you get in trouble. Or, as long as you avoid the vines entirely, you can just glide through the entire course to the end.
