Koko is swinging around in the Jungle, talking with the Pokémon and making sure he doesn't end up near the Great Tree, where the Zarude Pokémon live.

As he swings on the vines and jumps from tree to tree, he sees a figure. They weren't Pokémon, instead they looked like what he was. He swung over to the figure and look down at them from the tree.

"Za?" He whispers, so the figure doesn't know he's there. Since he was raised by a Zarude Pokémon, he couldn't really speak human language.
