If you listen to the first six "intro" sounds in the sound test, listen for a few seconds after the instructions and normal reports. You will hear Tiny give you random useless facts ("Poison Arrow frogs are the world's most poisonous animals"), a "special voice mail from a very special little girl," and a hilarious recording of the game testers singing Tiny's "Tiny Boy" ending theme song.

When you kill Big Bart in the first level his hat will be laying there waiting to be put on. If you get killed you will lose the hat.

Hold L1 + L2 + R1 + R2 + Left + Circle + Triangle + Square and press X at the options "Stamper" menu. The cheat code entry screen will appear.

When you get to the "Stamper Menu", go to the options screen. When you are there, hold R1, R2, L1, and L2. You will get to the code menu. Enter " TANKODOOM" to get invulnerability.

On the cheat menu, enter the following codes:

TANKODOOM - God Mode

WEAKROBOT - Increased Attack Power

TINYTINY - Little Tiny

FEATHER - Low Gravity

AAAAAAAAA - Disable Cheats
