ChuChu Rocket! Cheats

When you're on a credits screen (i.e. after completing a series of 25 puzzles in Puzzle 1P mode), hold B and the credits will scroll a little faster.

Every time you visit the Help section (which is the ChuChu Rocket! ''Homepage''), more of the Help section becomes revealed.

1st Visit: Various Modes
2nd Visit: Make your own puzzles!
3rd Visit: Battle technique
4th Visit: Download corner
5th Visit: Puzzle technique

The Download corner is the most intersting.
You can download three different Mice-types and Cats-types, so instead of you using the basic ChuChus and KapuKapus, you use Cows and UFOs, for instance.

1 : Mice-Cow Cats-UFO
2 : Mice-Balloon Cats-Pin
3 : Mice-Snow Cats-Fire
