|After Final Boss (given to you when beaten)||0621|
Hint: The true final boss
When you defeat the final Boss in level 5-8, you will be transported back to level 5-1 if you have not found the key in an earlier stage. You will find the key by shooting at crates in levels 5-1 through 5-7. Once you uncover the key, shoot it and your score will be displayed in gold instead of white. Now when you defeat the Boss in level 5-8, you will be able to open the door to the true final boss, El Niño.
