After you step inside a certain area in Chapter Two of Planet of Lana II, you will find several large pieces of Ore. These rocks are covered in a Green Gas that is very deadly. The Ore blocks your path, so you must find a way to clear the air to move forward.

Using Mui as a Shield

You can use Mui to make the area safe for a short time. Walk up to the Green Gas and have Mui stand right next to a piece of Ore.

When Mui is in place, the gas will vanish for a little while. This gives you a chance to pass by safely.

Moving the Rocks

While the gas is gone, you can also move the Ore out of your way if you need more room. Work your way through the area by placing Mui next to each rock one by one. This will clear a path that leads you upward to the next section in Planet of Lana II.
