Pikmin 2 Cheats (Xbox)

Unlock Challenge Mode 

To key to unlocking Pikmin 2's Challenge Mode (for one or two players) lies in the game's
third zone -- the lake area. Once you have unlocked it, grab a group of yellow and red
Pikmin as well as a handful of white Pikmin (to dig up hidden treasures along the way).
No blue Pikmin needed. Fight the electric bugs and fire emitters with the matching Pikmin
and make your way to basement level 5. Fight the mechanical spider with a small group of
yellow Pikmin: throw them at the spider's body, then call them back to you and move them
out of the way when the spider is stomping its feet. When you have beaten the spider, a
key (literally) appears. Have the Pikmin bring it back and exit the level by jumping into
the geyser. The Challenge Mode will now be available for selection from the main menu. 

Easter Egg: Title Screen Fun 

At the title screen (where it says "press Start"), press the X button to make a beetle
appear. Once the insect is on the screen, you can use left and right on the C-Stick to
turn it and forward to move. If you move the bug into the Pikmin that make up the logo,
they will "interact" with the bug. 

Press Y to make a Chappie appear. You can move it around the same way and press Z to make
it eat Pikmin. To get rid of the creatures, press the L button. 

Press R to make the Pikmin run around the screen and then rearrange themselves to form
the word "Nintendo."
