SpongeBob introduces Gary to Patrick by playing tag, and they decide to have a sleep-over together. The next morning, Gary doesn't want to leave Patrick, who concludes that Gary wants to be with him and claims him as his own pet. SpongeBob is heartbroken, and out of jealousy attempts to find a new pet to show to Gary that he doesn't need him. At first, he gets Rex, a worm, who immediately abandons him and leaves on a bus. Next, he gets Lary, a wild snail who acts viciously hostile toward him.
Later, Patrick and Gary come to SpongeBob's house to do his laundry, and Gary crawls into the washing machine after Patrick's pants. SpongeBob inspects this and realizes that Gary only wanted the cookie in Patrick's pocket. As SpongeBob and Gary, now reunited, go outside for a walk, a heartbroken and defeated Patrick stares after them and shouts, "Gary? I thought what we had was special!" Patrick is heartbroken.

SpongeBob, in a throwaway joke, reveals that he has another pet snail, "Jerry", a photo-realistic land snail.
This is the tenth episode to have flowers in the title card background.
SpongeBob reminds Gary that he took care of him when his eyeballs were sore. Closed captions alternate between "sore" and "tore" in different airings.
According to a SpongeBob Encyclopedia book in the pets section, it says Lary is the "pet from hell".
A smaller version of SpongeBob's wringer can be seen when Patrick is placing his basket of clothes on the table.
When the time lapses from night to day right after the "sleepover", a human finger is visible in the water right below the island, this is because the island is in Tom Kenny's pool.
In the beginning, SpongeBob is playing tag with Gary. When he runs up his house, an extra window is seen next to the upstairs window.
Rex, SpongeBob's pet worm leaves on a bus. In early airings, this bus had obvious jellyfishers on it. By default, that makes this currently the final epsode to feature a bus full of jellyfishers.
Lary made an appearance in Lights!Camera!Pants! as Sneaky Hermit's pet.
The face SpongeBob makes when he says "Who's a good boy?!" to Rex can be seen on various SpongeBob licensed products, including the newer packages of SpongeBob-shaped Kraft macaroni & cheese. It's accompanied by the slogan, "grin and square it!".
This is the first time Rex appears. The second is in As Seen on TV but Mr. Krabs called Rex's original name Mr. Doodles.
Patrick had no right to take Gary considering SpongeBob is Gary's legal owner. So basicaly the whole time Patrick was commiting a crime by "stealing" Gary.

When SpongeBob gets Lary, he states that Gary's name "will not be mentioned in this household". Quickly after telling him this, SpongeBob mentions Gary's name.

It is unknown whatever happened to Lary the snail.
When SpongeBob's alarm goes off, he doesn't press the button to make it stop, the alarm stops by itself.
