Pikmin 2 Cheats

While looking at an enemy in Olimar's journal, press the Z button to encase it in stone for a little while. This doesn't work on harmless plants.

Assemble 20 of each of the 5 colored Pikmin into a single group to hear them hum the Japanese Pikmin 1 theme song, Ai no Uta by Strawberry Flower.

Press X to make a Bulborb walk in, control it with c-stick and eat with Z.
Press Y to make a Flint Beatle appear, control withc-stick.
Press L to revert everything back to normal (except for any eaten pikmin)
Press R to make the Pikmin say Nintendo.

As you continue to collect treasure, you'll eventually come across one called the Gyroid Bust. This refers to the Gyroids, collectible items featured in the game Animal Crossing.
