Pikmin 2

• 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."
• When browsing the Piklopedia, press the Z button to spray extra bitter spray on the enemy, thus freezing them!

If you bring 20 of each color Pikmin with you, the song they hum will be the hit song from the Japanese commercial for Pikmin. It will work both in the main levels and in the caverns where it will replace the Luigi's Mansion theme they otherwise like to sing.

If you come across a strange beetle that pops out of the ground, simply throw a purple pikmin anywhere around it and it will drop whatever it has.

Late in the game, you will receive a letter from a mysterious stranger. It invites you to go to a hidden URL: www.nintendo.jp/p/c234/. The website contains a simple Q&A/survey that mixes fun questions with survey inquiries. Depending on your answers, you are likened and matched with a creature from the game.

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.
