=>Bonus Stage: When the ten thousands digit of your score (10,000) is 7, fly
home with Launchpad and you will get to play a bonus stage. For example, a
score of 70000, 75000, or 170010 points would work.
=>Pass Amazon Statue for Free: In the Amazon level, you will find a large
grey statue which demands money in exchange for passage. Opt not to pay,
then return a little left until a plunger-tossing enemy appears. Stand
under the rope near the top of the screen and bounce off that enemy to jump
up to the rope without paying the statue.
=>Extra Ending: Earn at least one billion points and beat the game for a
different ending.
