Excuse me, but I`m British, so I don`t know the clues from Burger King, or the story of their rivalry.
However, from what I can tell, it involves Plankton and Krabs finding the long lost Krabby Patty formula as kids.
However, I`m not sure if Krabs cheated Plankton out of his share of the formula or not.
If anyone could tell me the clues from Burger King, maybe i could guess.
