Xenoblade Chronicles/Bionis Leg

This landscape may look big from your point of view, but once you get the hang of it, you won't get lost in this. The first thing that Shulk and Ryen see is a buggy.

Meeting Sharla and Juju
When you get to the buggy, you see a vision of triceratops attacking the kid? Anyway, you have to go to where the water is on this place which is not far. So take care of the creatures then once the cutscene is done you'll go to the Refugee Camp which is opposite to what is Rho Oasis. On the map that's basically south from that location where the heart-to-heart is.

It would be good to listen to Sharla's story to trigger Juju's disappearing and also a vision of Juju and Sharla getting clamped by the mechanical octopus. Sort of. As this is the norm, Sharla will now support you because of her great healing skills via rifle.

Battling the mechonis with legs
If your having trouble here's the directions: Go right outside the Refugee Camp and if you're into upgrading your experience, take down the Mechons which might help you lead the path to where Juju is. You'll reach the Raguel Bridge and take the right side along the Maguel Road. Once you reach the other end, you should see a spiral shaped valley which is called Spiral Valley on the left of where you are.

Once you reach the Spiral Valley a cutscene ensues. You now have the speed ability meaning any character can dodge attacks for a brief time. After the first battle, go up to continue battling. But make sure you finish up your sidequests or you might have no chance of defeating it.

If you think it's over, there's one bit of business left. Xord comes down for a brief fight. Sadly after the battle, Juju is taken to Colony 6.

After the cutscene, your team should head off to Colony 6. So from Spiral Valley in which Juju was last taken, go south to where there is a bridge for you to get across. In Colony 6 after another cutscene go north to take on sidequests and maybe go back clear up remaining ones before going down the elevator and going through the Splintered path via drainage area. Get ready for some Mechon mashing!
