152b - Perfect Chemistry (136)

The episode begins with Sandy and SpongeBob at the Treedome working on a teleporter to teleport Sandy's acorns to Texas. Unfortunately, the teleporter fails.

The scene then changes to the Chum Bucket where Plankton is manically laughing for he just completed a new invention. Karen and Plankton converse for a while, until Plankton enters the invention and becomes a gas. He travels across the street to the Krusty Krab and slips through the door and into Mr. Krabs' office. Mr. Krabs is revolted by the smell and uses a fan to blow him away. Meanwhile, Plankton is blown to the Treedome where SpongeBob instantly recognizes him and Sandy is impressed that he was able to turn himself into a gas.

Sandy and Plankton converse while Sandy decides to come over and help combine Plankton's invention with Sandy's teleporter. While at the Chum Bucket, Sandy and Plankton talk about science while SpongeBob is upset and feels left out. Sandy then tells him that he can be the test monkey.


Plankton and Sandy hook cables up to SpongeBob and teleport him to the Krusty Krab. Unfortunately, only his eyes teleport. Squidward is frightened and tells Mr. Krabs who thinks that Squidward just has bad gas. Plankton and Sandy teleport SpongeBob back to the Chum Bucket. This continues until SpongeBob's entire body gets teleported. Plankton then traps Sandy and SpongeBob in a cage and teleports him to the bottle where the Krabby Patty formula is stored. Then, Sandy teleports the Krabby Patty formula back to her and SpongeBob, leaving Plankton stuck in the bottle. Sandy says that she knew Plankton was in it for the formula the entire time. The episode ends with Sandy bragging that she cannot be fooled and laughing evilly.

  • Although this episode premiered in 2011, it was made in 2010 according to the credits.
  • Even though Karen and Sandy have been near each other in many previous episodes, this is the first episode where they are seen communicating.
  • The title is a play on the dating term "perfect chemistry."
  • This is the last episode where SpongeBob's voice is high pitched.
  • This is the last episode of season 7 in production order.
  • "Patrick SmartPants" re-aired when this episode premiered, but it now airs with "Big Sister Sam" as deposition.
  • It is impossible for SpongeBob to know that his mouth and body were facing Squidward unless the transported parts have a mind of their own. But the parts were always sure where Squidward was, and without ears and eyes, it should have been impossible for the parts to find Squidward.
  • This was the only episode where Sandy teamed up with Plankton.


  • The episode continually switches between day and night. When Plankton first meets up with SpongeBob and Sandy, it is night, but when it cuts to the Krusty Krab, it is daytime. This happens again in the final shot, where it is daytime at the Krusty Krab, but when it cuts to Sandy laughing evilly, it is night.
  • When Sandy waved her torch around, no one was affected by their lack of eye protection.
  • When SpongeBob picks up the Krabby Patty secret formula, Sandy is right next to SpongeBob looking at it.
  • Closed-captions misspell "Krab(s)" as "Crab(s)."
  • When Plankton puts on his first pair of goggles, he looks into them since they are big to him. Later in the episode, they change. His second pair of goggles (goggle, since he only has one eye) fit him fine. Sandy's goggles change as well. This could be because Plankton did not like his first pair of goggles.
  • When Plankton transports himself into Sandy's treedome, he does not have a water helmet on and he seems to be breathing normally, despite being a sea creature.
  • Normally when the inside of SpongeBob's body is shown it has holes, but in this episode, it does not.

Running gags

  • After SpongeBob's body parts disappear when Mr. Krabs is trying to believe Squidward, a fart noise was heard and Mr. Krabs thinks it was Squidward who did it and SpongeBob wanting to be called "lab partner."
