Pyramid

As you arrive at the Sphinx, take a look in your inventory and re-read the Hieroglyph Copy.

This will show you the pattern in which you need to touch the buttons in front of the Sphinx.

Each number corresponds with the placement/order of the buttons that you need to touch. The top one is the first one you should touch.

After completing the pattern the doors to the Pyramid will open just north of the Sphinx.

Enter the pyramid and you'll walk up and down the ancient corridors in search of the Hawk Eye.

Be careful as some of the enemies can be a little tough here. Specifically the Shattered Men and the Petrified Royal Guards can be trouble.

You will come across a casket that looks like it's covering something.

Go further into the pyramid and you'll find a casket blocking the door. Heal up and check it to start a battle with the Guardian General. Be sure to throw everything you've got at him since he's the toughest battle in the Pyramid.

Go through the doorway and you'll see a switch on the floor. Step on it and something will move up above.

There are a few good items in the area so make sure you look at the map to find the ones you want to get.

Specifically you'll probably want the Rain Pendant, Diamond Band and the Bag of Dragonite. 

Go back to where the casket was and you'll now see a hole you can drop down.

There you'll find the Hawk Eye.

As you exit the pyramid, Star Master will appear.

Star Master tells Poo that he must show him the way of Starstorm.

Poo reassures Ness that he will return to the party.

With Poo gone, head just north of the pyramid exit and you'll find the guy who has the Key to the tower.

There are also a few people selling some pretty handy items.

This is the first time Jeff will be able to buy some Multi Bottle Rockets. Load up on those bad boys.
