You can skip levels whever you find a life recharge icon above a lava bed. To do so, lose most of your lift (all but the last notch). Now jump in the lava and recharge your life at the same time. If you did this correctly, you should warp to the next level.
Passwords
Make B.O.B.'s life a little easier with this complete set of passwords. For an added bonus, replace the second number in any password with '9'. You'll gain several remotes and other bonuses.
At the "Foley High Tech Systems" screen, quickly press A + B + C on controller two. You should hear a chime. Start the game and you will have infinite lives, all weapons, and all remotes!
Secret Room
On the first level, stand beside the stars that enable you to pass the level. Use the helecoptor or spring pads to go through the ceiling and into a secret room. Here you will find all the weapons and remotes.
