Cresselia appears in the grasses of Sinnoh (like the three Legendary Dogs and Mespirit), but only after you go to Full Moon Island. To get to Full Moon Island, you must get the National dex, and go to Canalave City. You must then search for the guy that takes you to Iron Island's family. Next, go to his house, and talk to his son, who is asleep, and having a nightmare. Then, talk to the sailor's wife, and talk to him after. He will then take you to Full Moon Island.

This is done on the level Metropolis and is easiest when done on Co-op. When you start out, cross the bridge. Take out every enemy and even your marines. When you're near the end, Cortana will say something about a "Welcome Party". Three Banshees and a few ghosts will appear. Take them all out. Then 2 Wraiths and 2 Banshees will appear. Take out both Wraiths, and only one Banshee. Have Player 1 continue through the tunnel, but have Player 2 stay outside and distract the Banshee. Once Player 1 reaches the area with the circular opening (a Jackal with a Beam rifle is present), take out the Jackal and head back to where Player 2 is.

Here is the hard part. Get the Banshee to follow both players into the tunnel. Do not board it yet! The first few times it will come at you and fly back out, but stay where you are. It should come back after you. (If it doesn't, go back outside and try again). Eventually, you'll have to get it over two road blocks. Once it is past the second one, have both players stand near the entrance of the room where Player 1 took out the Jackal. It should fly at you and get stuck. Shoot off both of its wings so it can fit thru. Have Player 1 walk slowly in front of the Banshee, making it follow him. Player 2 should be behind it, gently pushing it. Take it to the left and get ready to board it. As soon as you hit the checkpoint, the Elite in the Banshee will disappear. You only have about a second to get in before the Banshee also disappears. Both players should press X quickly. If done right, one of the players will be driving the Banshee!

Take it outside and directly up. Very high in the sky are two skyscrapers with two bridges connecting them. In the middle of the bridge closest to you, there is something that looks like a plasma rifle. It's actually a Scarab gun! It has infinite ammo, so have fun. Just don't aim at the ground.....

In the level Arbiter on Legendary. Once you get to the first banshee section, fly immediately straight down all the way to the bottom of the map. In one of the cracks where the large cylinders connect to the station. There will be a circle of grunts dancing around a skull. When you pick up the skull; it will say Grunt Birthday Party on the screen. Now when you kill a enemy with a headshot, they will blow up like a plasma grenade was stuck to them.

To get rid of this feature use the same method as the blind mode.

A skull similar to the one that activates blind mode can be found if you Start on "regret". After the first lift ride (before the first underwater elevator), grenade jump from the front awning of the lift to the ledge in front of you (the one with two turrets).

Grenade jump AGAIN onto the next ledge.

Make your way to the back of the building. On Easy, you'll only find the skull. On Legendary, however, 2 invisible Elites carrying swords just shake their heads wildly, ignoring you completely.

At the beginning of Outskirts jump on top of the light on top of the door with a crouch jump, then jump to the left platform. Turn to your left and go down the long dark corridor and pick up the skull; it will say blind and your screen will flash black for a while. In this mode you can not see your weapon, body, shields, ammo, or radar. To get rid of this feature use the following method: 1. Turn off your XBOX or Save and Quit. 2. Go to Campaign and select level and choose Cairo Station. 3. Skip the cinematics and then Save and Quit. 4. Go Outskirt and your hud is back.

It's on the level "Metropolis" on any difficulty I do believe. Use the same method to get a Banshee through the tunnels as you would if you were getting the Scarab Gun. (See the corresponding cheat for more details)

Now take your Banshee away from that half-dome thing and fly through the level using the same path you would as if you were walking. Once you get to the highway where the Warthogs are fighting the Ghosts, keep flying straight toward the half-demolished building. Fly into it and go to the bottom level. Behold! A giant soccer ball! It's great fun to mess around with, especially if you have the Scarab gun.

On the level Midship, go to the top where the sword spawns. Now walk to the doorway which doesn't have a big roof. Look up and you should see an outline of a bunny!

Unlike other Zelda games (where you got attacked if you hit the Cuccos), in Twilight Princess if you hit a Cucco about 8 times, you'll be able to control it for a short period of time.

If you visit the Fishing Hole in Upper Zora's River, there's a mini game Hena will let you play for 5 Rupees called Rollgoal. If you make it past 1-8, you'll be rewarded with the Frog Lure. However, if you keep going and beat the entire thing, up to and including 8-8, you'll be able to play the special-edition version of Rollgoal. You can choose any level, the cost is free, the time limit is raised to 4:00:00, and you cannot win any Rupees. Also, as an added bonus, once you beat 8-8, Hena will fill your wallet completely!

If you are trying to hatch an egg and have a Pokemon with the Magma Armor or Flame Body ability in your party, then it will cut the hatch time in half.
