Squidward notices that the neighborhood is unusually quiet, and assumes that SpongeBob is gone for the evening. Back in his house, Squidward tries to relax and watch some smooth jazz on public television, only to be distracted by SpongeBob and Patrick, who emphasize that they are trying to "enhance'" Squidward's evening. Eventually, Squidward lets SpongeBob and Patrick watch with him, only to be bombarded with questions. At last, Squidward is fed up and leaves Patrick and SpongeBob watching his television.
Departing the neighborhood on his bicycle, Squidward is hit by a truck of cement and flies off into Jellyfish Fields, where he stays for five days. SpongeBob and Patrick are jellyfishing where they spot him and decide to adopt Squidward, who they consider a wild animal and refer to as "Smelly."
Back at SpongeBob's pineapple house, Gary attacks Squidward and SpongeBob determines that it is dangerous for Smelly to remain in his household. Patrick decides to take Squidward under his wing, and plays a game of catch with him at his rock, but ends up calling Animal Control, who come and take Smelly to the zoo. There, SpongeBob is horrified that everyone is treating Smelly so cruelly, so that night, SpongeBob and Patrick break into the zoo and plan to free Squidward. However, they are caught by Animal Control and SpongeBob and Patrick only manage to lose them by going underground.
After a while, Patrick sees the light and the gang find themselves in a jungle-like landscape. SpongeBob remarks that the creatures around them look just like Smelly, so they leave Smelly with his real family and return home. The creatures accept Squidward as one of their kind, and as Kelpy G starts playing his clarinet, Squidward's cement cracks open and he simply says to the creatures, "Um...hi."

- This episode is available on the Season 4 Volume 2, Complete Fourth Season, First 100 Episodes, The Third & Fourth Seasons, The Best 200 Episodes Ever, and Nautical Nonsense and Sponge Buddies (Turkish) DVDs.
- This episode was released on the Season 4 Volume 2 DVD box set a few days before it aired on TV in the USA.
- Although this episode premiered in 2007, it was produced in 2006 according to the credits.
- This episode is similar to "Jellyfishing," where in both episodes, Squidward rides his bicycle to get away from SpongeBob and Patrick, but ends up getting injured and unable to talk. Thus, revealing himself at the end by his uniform cracking open.
- The squid on TV looks similar to Dream Squidward from a dream in "SquidBob TentaclePants."
- When SpongeBob and Patrick are watching TV, the show plays the same music heard while Patrick watches TV in "Rock-a-Bye Bivalve" and Patrick says, "Oh wait! I think I've seen this before. This part's funny." It is likely the same show Patrick watched in that episode.
- Patrick says that Squidward hates pets. However, in "The Great Snail Race," Squidward shows great care for his pet snail.
- This is the first appearance of Kelpy G.
- This is the second episode in which Squidward has an accident while riding a bicycle in an attempt to get away from SpongeBob and Patrick. The first is "Jellyfishing."
- This is the third of four episodes transcribed as a comic into the SpongeBob SquarePants/Tokyopop book Mistaken Identity. The other three were "Once Bitten," "That's No Lady," and "Rule of Dumb."
- Coincidentally, all are season 4 episodes.
- The smooth jazz song is heard once again in "A Flea in Her Dome" and "Enchanted Tiki Dreams."
- In this episode, Kelpy G's name is not mentioned. However, in "Smoothe Jazz at Bikini Bottom," it is.
- However, his name is revealed in the closing credits to this episode.
- This was the first episode to premiere in 2007.
- This episode premiered on Andrea Martin's 60th birthday and five years after SuperSponge was released in Australia.
- This episode was paired up with "Squilliam Returns" during the Massive Monster Mayhem Marathon.
- Throughout the whole episode, SpongeBob and Patrick never found out that Smelly was actually Squidward.
- This is the second episode where the Bikini Bottom Zoo appears. The first was "The Smoking Peanut."
- The title is likely a reference to the 1982 John Carpenter film of the same name.
- When Squidward is taken in by the other animals at the end, SpongeBob says to Patrick, "But he's with his own kind now, where he belongs, and with that, let us go back to where we belong." This is a reference to the ending of Disney's 1967 film The Jungle Book.
- At the beginning of the episode, the path to Patrick's rock is missing.
- Squidward's grape juice box background is yellow and Patrick's is purple, but later, they are both purple.
- Squidward asks no one in particular if a hard-working squid could get a break. However, Squidward is an octopus, not a squid, and he does not even care about his job at the Krusty Krab.
- Patrick never says where his house is, but somehow, the cops showed up right where they needed to.
- Kelpy G's clarinet in his song sounds more like a saxophone.
- The TV description for this episode says that Squidward gets in a bicycling accident and gets covered in mud and leaves. However, he actually gets covered in cement.
- When Squidward hits the cement truck and rolls down covered in cement, the scene changes from a street to a grassy field.
