The AAA is a glitch that allows you to take alternate characters into some sections of the game they wouldn't normally be able to access, as long as the level starts from a saved game. The glitch itself won't be very useful in any%, but could be useful if a newgameplus% category is made. The process for performing the glitch is as follows: -Save at the level you want to bring a character into. -Go to the Mu Continent and change your characters (also possible at the beginning of Atlantis, but easier with the Mu Continent). -Exit to the title screen and reload your save. (Do NOT take the bus or soft reset, as this will change the character values back to Spongebob and Patrick) -If done correctly, once you enter the game from the hub world, you should be in control of the new character.

Places where this can be used: -Caves (Any combination can complete the escape sequence, but only Spongebob and Patrick can do the first run) -Bikini Bottom (Patrick and a double jumper is required to pass) -Sandy boss (Yes, you can fight Sandy with Sandy) -Anytime in Mu Continent (Useless in this case since there's always a character switcher at the beginning of the levels, but still works nonetheless) -Atlantis (Beginning is the same case as Mu Continent, but also works during the escape where there's not a character switcher) -Plankton boss

Unfortunately, there seems to be a reset value that defaults character choice back to Spongebob and Patrick before the Royal Guard boss (despite the fact that you normally shouldn't be able to take other characters into this part of the game anyway), so it's impossible to take alternate characters into that fight without hacking/modifying the game.
