His plan: to create an envelope in a bottle that looks like the secret formula and use a catapult to throw the decoy into the Krusty Krab and when everyone takes the decoy as the real thing: he'll take formula and once they realize that was a trick, he would have already made enough Krabby Patties to put Krabs out of business! Plankton wakes the next morning to see that the catapult and his decoy formula are destroyed. An enraged Plankton vows to find out who did it and to have his revenge on them. From then on, the game becomes a black and white story narrated by Plankton. Plankton goes into every location and looks for enough clues to figure out if anyone is guilty.
