part 3 is out~! yay~! grats as aways. now....
So, the path is pretty straightforward. There's only one way, so just weave your way through the overgrown forest for awhile. Eventually you'll run into a Team Meteor Grunt [i mean, who else would be behind this garbage?]. There should be a Light Shard right by him. Continue through, battling more Team Meteor Grunts as you go.
Now, you should come to see a hooded character before a fancy-looking Tangrowth machine. I highly recommend that you use the Light Shard and save the game, as the battle ahead of you is not easy.
When you approach the scene, you'll meet my personal favorite villain of the whole game. You'll notice that their speech is a bit nonsensical, scattered and distorted. This is because they have multiple personality disorder, with three distinct personalities shining through: Zero, the violent one; Eve, the logical one; and Lumi, the sweet one. Collectively: ZEL. Their speech is much easier to follow when you realize that the text capitalizes the letter of each personality speaking at a given time [creating Zel, zEl, and zeL]. ZEL explains that this Tangrowth "Pulse" machine is the source of the rapid burgeon of plant life in the area. They'll then proceed to challenge you to a battle with it.
