  • Thursday



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 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's office. Mr. Krabs is revolted by the smell and uses a fan to blow him away. Plankton is blown to the Treedome where SpongeBob recognizes him and Sandy is impressed that he was able to turn himself into a gas. Sandy and Plankton converse and 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 sad and feels left out. Sandy then tells him 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 scared and tells Mr. Krabs who thinks that Squidward just has bad gas. Plankton and Sandy teleport SpongeBob back to the Chum Bucket. It goes like that for a while 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 said she knew Plankton was in it for the formula all along. The episode ends with Sandy bragging that she cannot be fooled and laughing evilly.


  • When Spongbob's eyes are teleported, he walks around with his arms out, and says, "Hey, who turned out the lights?" this is a reference to the Doctor Who two-part episode, "Silence in the library/Forest of the dead".
  • There is a talking piece of broccoli in Plankton's machine.
  • This episode might have a reference to Phineas and Ferb. The reference could be Squidward trying to show Mr. Krabs one of Spongebob's transported body parts but it disappearing before Squidward could show Mr. Krabs.
  • Patrick SmartPants re-aired when this episode premiered, but it now airs with "Big Sister Sam."
  • Closed captions misspell "Krab(s)" as "Crab(s)".
  • This is one of the episodes that have a lot of caption errors. When SpongeBob says "Hi Squidward.", captions says "Hi Squidworth."
  • Sandy and Plankton both appeared to be using either MIG or TIG arc welding on their inventions. However, besides the head shields, neither is wearing any protection (especially dangerous for Sandy, who is covered in fur).
  • The torches had a flame coming from the tip, but MIG and TIG welding utilize an electric arc instead.
  • When Sandy waved her torch around no one was affected by their lack of eye protection.
  • When SpongeBob picks up the Krabby Patty formula, Sandy is right next to SpongeBob looking at it.
  • The title card is the same as "Porous Pockets" but it is purple, and the triangles are upside down.
  • There is a real raw vegetable like a broccoli sitting inside of Plankton's invention next to him. Also this is the 2nd time that part of this episode has one item that's real, the first was "Cephalopod Lodge" when Spongebob pull out a larger sock, that it's real.
  • When Spongebob is wearing the Test Monkey suit, this would mark the 2nd time a character is wearing one of the primate costume. the 1st was "I Had An Accident" when Patrick was in a Gorilla costume.
  • While Plankton is a solid, he must stay on ground because of the law of gravity. As a gaseous substance, he is able to stay off the ground and float around but can remain his distance from the ground.
    • While Plankton is a gas, he would lose some of his molecules since it disappears.
    • Strangely, the gas doesn't expand. The most likely hypothesis is that the cold, deep water at night keeps it from expanding.
    • After Plankton thaws, he is able to survive without wearing a miniature water helmet.
  • This episode marks the season finale of season 7.
  • This is the second time Plankton visits Sandy's Treedome, both times being involuntary. The first time was Someone's in the Kitchen with Sandy; she takes a Krabby Patty home, unaware that Plankton is hiding on the bun. This time, he turns into gas and is blown away by Mr. Krabs' fan after being mistaken for flatus.
  • Sandy seems to have forgiven Plankton, or forgotten what he had done to her in Someone's in the Kitchen with Sandy.
  • The process of going from solid to gas is sublimation, which Plankton achieved initially. However, when he was placed into a jar and frozen from a gas into a solid, the process is known as deposition.
  • It is impossible for SpongeBob to know that his mouth and body was facing Squidward, unless the transported parts had a mind of its own, but the parts were always sure where Squidward is, and without ears and eyes, it is impossible for the parts to find Squidward.
  • It is revealed SpongeBob possesses knowledge of what a monkey is. He must have learned this from Sandy, considering she is a land mammal.
  • When Sandy says, " new lab partner", SpongeBob's heart breaks showing he might have a crush on Sandy.
