Use the keys in alphabetical order until you get to the piece of dialogue that says "yes ma'am princess ma'am", then hit the space bar and get my outro. That is pretty much it.
This is part 2 to Adventures of Frank and Frogger and a special shoutout to @paintdemon for giving me the idea to do this in the first place when I had no idea about what to do at all, if you watch my outro then you will see how you can get a shoutout at well.
