Plot
The episode begins with Mr. Krabs at his desk and whistling with pickles. SpongeBob enters and they briefly discuss Mr. Krabs' obsession with money. Then, they both leave the room. Plankton pops out of the pickle jar. He hops on top of the secret formula's safe and attempts to open it. It does not open, even after Plankton studies the combination. Plankton soon falls off onto the floor. Mr. Krabs bursts in and, mistaking Plankton for a pickle, he puts him in his mouth, and then spits him out, making Plankton bruised and injured all over. Approximately ten hours later, Plankton arrives at the Chum Bucket, when Karen suggests that Plankton should get a second eye to see the safe's combination more clearly as she states that with only one eye, he lacks depth perception. The two-eye surgery Plankton attempts results in him turning into a creature with many eyes that combine to make one huge eye. On the second try, Plankton's new eye turns into an eye-creature with robotic legs. Finally, Karen says Plankton needs teardrops successfully complete the procedure, so he makes himself cry, only to be told by Karen that he needs teardrops from a person that has two eyes. So, Plankton pursues SpongeBob to get him to cry. After finding him having a picnic, Plankton tells SpongeBob a sad story about himself and his milk spilling and Plankton actually does what happened in the story, causing SpongeBob to cry uncontrollably. Plankton gets the tear sample he sought after and begins the third surgery, in which Karen drops SpongeBob's tear liquid into Plankton's eye. An eye similar to one of SpongeBob's sprouts from his face, and Plankton sees things as SpongeBob does, that is, all happy and full of optimism. He goes after the secret formula but instead stops to admire the beauty of his surroundings.

When Plankton arrives again at the Chum Bucket near the end of the day, Karen realizes that the second eye is giving Plankton a split personality, calling him "Neevil." Plankton is stubborn and denies her claim, however, and tries to disprove her by stealing the formula, but Plankton is, once again, distracted by Bubble Bass, who is in need of a rescue from a burning building. After the rescue, Plankton randomly finds the formula on the ground and returns it to Mr. Krabs like a nice person, but Mr. Krabs, however, thinks Plankton is playing a trick. It is now that Plankton finally realizes that he is actually non-evil now, so he tries to remove the eye several times but fails.

Plankton returns to the Chum Bucket and falls into despair. However, a surprise party is thrown for Plankton's good deeds. It seems that everybody in town is at the party. As SpongeBob and all of his friends hug Plankton, the second eye pops off. Plankton becomes evil again and drives out the party-goers with red infrared security attack lasers. The episode ends with Plankton bumping his head on the door because of his depth-perception issues caused by having only one eye, as the episode ends.
