Squidward is dreaming he is a great musician. Suddenly, his alarm clock goes off, waking him. He prepares for another day at the Krusty Krab. SpongeBob gets ready to go to work also. SpongeBob sees Squidward and asks him why he's playing his clarinet. Squidward says he's practicing for his performance tomorrow. Squidward keeps walking to work while SpongeBob visits Sandy. He finds Sandy with a machine that can transport things. Sandy shows SpongeBob how it works by teleporting an apple to Mrs. Puff's desk. SpongeBob asks Sandy if it can transport him to the Krusty Krab. She allows him to try it. When he gets there, part of Squidward's arm gets stuck in him. Suddenly, the machine malfunctions, and SpongeBob and Squidward are transported back morphing them together. Sandy sees what has happened and is terrified. When they walk out, SpongeBob has his normal head/body, while Squidward's head is sticking out of the upper left. SpongeBob's left arm and right leg are Squidward's. Squidward tries to get out, but he can't. He is scared of the fact he and SpongeBob are stuck together. But SpongeBob they can be together forever now, scaring him more. Suidward asks Sandy to do something. She decides to zap them back in the transporter. She zaps them to a school, a hospital, and Mars, but they are still stuck together. Squidward says she has to get them unstuck. Sandy tells Squidward she was working on a new invention, but it's not ready. He tells her to hurry because he can't stay stuck to SpongeBob. She tells him to stay calm, and she'll continue working on it. Squidward and SpongeBob are riding to work on a bike. SpongeBob says he'll drive, but Squidward keeps getting hit by the wheel. They crash into the kitchen and Mr. Krabs asks what happened. They stand up revieling their morphed body. Mr. Krabs just tells them to get to work. They try working, but they can't because they're stuck together. Mr. Krabs kicks them out and tells them to not come back, until they fix their problem. SpongeBob says they still have each other, and Squidward angrily says that's how they ended up like this in the first place. Squidward practices playing while SpongeBob is sad. A surfer guy passes and says "Rock on, Freaky Bro". They run over to Sandy's and ask her if she's found a way to fix them. Sandy says she has invented the Molecular Seperator Ray. Squidward is ready to be free, but Sandy says she's not finished. She says she'll probably have it ready the day after tomorrow. Squidward frantically tells her he has a performance tomorrow. So she tells him she will have it ready before he goes on. SpongeBob and Squidward try to go to their own houses, but they can't due to being stuck. Squidward tries by force, but it pushes their houses together. At the clarinet performance, Squidward is wondering where Sandy is. He thinks about giving up, but SpongeBob tells him this is his big chance to be a star. He decides to wear a cloak in order to hide SpongeBob. He starts playing his clarinet, upseting everyone. A loose nail pulls the cloak off, revealing their secret. Amazingly, the crowd loves and starts cheering. Squidward finally knows what stardom fells like. Suddenly, Sandy shows up and tells Squidward she finished the device. Squidward tries to tell her not to, but she seperates the two, displeasing the crowd. Squidward starts playing his clarinet again, but everyone hates the sound of it. They leave in anger and disgust. Squidward says his one moment of fame is gone. He yanks the machine from Sandy and tries to reverse it. Sandy tries telling him that it's a very sensitive device. Suddenly, the machine breaks and Squidward is morphed. Squidward is seen at a psychyatrist's office. The doctor asks Squidward what the problem is. Squidward says it all started when he was born. It's revealed that Suidward morphed together with SpongeBob, Patrick, Sandy, Pearl, Mr. Krabs, and Mrs. Puff. He now looks worse than before.
The original airing had Squidward talking to a therapist after Sandy's machine exploded, and was horribly deformed and mishapen. This was cut from reruns due to being too gruesome. Eventually, the scene was restored and aired uncut for a few years. Recently, however, a complaint was sent, and the scene was removed once again. Despite this, the episode is broadcasted uncut in Latin America and the USA.

At the very end of the episode, the scene involving Squidward being fused with everyone was cut, only in certain countries, like Italy, Russia, France, and Germany, controversial for being a bit disturbing and disgusting.
Mr. Krabs says "Time is Money!", the same way in Wet Painters.
In the Brazilian dubbing, this episode is called "Bob Lula Calça Tentáculos", an adaption of the original name (Bob Lula stands for Bob Squid and Calça Tentáculos, Pants Tentacles).
In Greek, this episode called Καλαμάρης ο Πλοκάμιας which means "Squidward Tentacles".
Squidward's hair in his fantasy is similar to Kenny G's.
When SpongeBob and Squidward were fused together is a parody of the 1986 science fiction horror film The Fly.
A similar fusing occurred in a "Star Trek: Voyager" episode, when Tuvok and Neelix fused due to a teleporter incident into the character Tuvix. As the case with SpongeBob and Squidward, Tuvok and Neelix are quite dissimilar and could hardly be called friends. Also coincidentially, Paramount produced this episode 9 years before the SpongeBob episode was made.
Patrick appears at the end of the episode but does not speak, though he was heard cheering after the audience sees SpongeBob and Squidward fused.
At the point where Squidward is speaking to Sandy and says "I can't stay stuck to that yellow freak" and it zooms in on SpongeBob, the tentacle arm is colored yellow, instead of the usual blue-ish color.
At the recital, when SpongeBob convinces Squidward to perform fused, he uses the sponge arm instead of the squid arm. The same thing happened when they were riding bikes.
When SpongeBob and Squidward go to their houses, their arms switch sides.
Larry The Lobster was one of the characters who were fused together by Squidward, but he wasn't seen at the end.
