When Plankton, Karen, and SpongeBob throw a party, SpongeBob gets tricked into putting his face on a copy machine. Plankton puts the copier on "Scan" and it scans SpongeBob. He clicks print and makes a SpongeBob clone the next day and then he colors the tie blue with a marker.
Then the next day, at the Krusty Krab, the copy walks over to the real SpongeBob and they work for Mr. Krabs. Squidward goes crazy because he thinks he's dreaming, causing him to beat up customers and Mr. Krabs.
Plankton makes 305 more clones to ask for the formula but then after they find out what the formula is twice, one of them turn into a light gray hue. SpongeBob found out that one of his copy was made to steal the formula also. The copy rolled up into the shape of a burrito and then vanished in mid-air. As SpongeBob cries for his loss of his friends and Plankton asks the other copies about the formula, the other clones quickly vanishes. Mr. Krabs comes with the paychecks for the copies, and the final copy disappears. When Plankton comes out to find another SpongeBob, he asks for the formula before he disappears, but it was the real SpongeBob. SpongeBob is still sad for the loss, but Plankton says that the citizens are better with one SpongeBob. Squidward comes back and then squishes Plankton after trying to fly and Plankton says "Right on my keys." and the episode ends.
This is the second time Plankton asks SpongeBob to step on him. The first time was in "One Coarse Meal."
The SpongeBob copy that disappears when SpongeBob hugs him and yells, "No! Don't disappear!" is most likely Me Three, as he faded after Me Two, but before all the other copies.
This is the first time Patrick appears in an episode, without him communicating with SpongeBob, even though he was playing with SpongeCopies.
This episode also confirms, as of this episode, Plankton has no children.
This episode must take place before "Married to Money" because in that episode, Mr. Krabs claimed he never told anyone the secret formula, and in this episode he had no problem telling the SpongeCopy's the secret formula. Or this could simply be a continuity error, or Mr. Krabs lied to Cashina.
This is the second time Patrick gets shredded by a lawnmower. The first time was in "Born to Be Wild."
