Exploding Manny:
Type blam when walking. Manny will explode then come back together.
LucasArts cameos:
Go to Rubacava in years 2, 3, or 4 and enter the tattoo parlor. Enter the back room with the refrigerator. Examine the poster with tattoo designs next to the cabinet. Max (from Sam And Max) and the Corley Motors logo (from Full Throttle) are featured as small designs on the poster.
Dying:
You cannot die at any time in the game. You will get sprouted by Hector. When this happens use the liquid nitrogen from the tattoo parlor on yourself.
Color pause with no characters:
Press [F1] to pause game play, then press [Alt] [Tab] to go to the Windows Desktop. Go back to the game and you will notice that the previously black and white paused screen will now be in color. Also, all characters will have disappeared.
Manny’s re-appearing cap:
At the beginning of Year 3, Manny will wear a cap. Press I to enter the inventory. Exit the inventory and notice that Manny has lost his cap. Enter the ship and he will be wearing his cap again.
Invisible characters:
Save the game during an intermission sequence (for example, when Carlie comes to claim the suitcase from Manny). Load that saved game. Some characters will be invisible, and you can only see the face of the character when it speaks.
