SpongeBob gets an invitation to his grandma's birthday party, so he decides to go, but then, he remembers that he needs to take care of Gary. First, he asks Squidward to watch Gary, but he refuses because Gary ate his kelp garden. Later on, SpongeBob asks his best friend Patrick to watch him while he is at his grandma's birthday party, and Patrick accepts. SpongeBob shows him a schedule of all the things he needs to do that involve Gary, which Patrick acknowledges and agrees to follow.
With the two now alone, Patrick does the first thing on the schedule: feed Gary. He grabs a bag of snail and checks if it is okay for him to eat by chugging down on all the food inside, much to Gary's displeasure.
While SpongeBob is at his grandmother's house, he gets distracting visions about Patrick doing bad things to Gary. Once SpongeBob is anxious enough, he calls home numerous amounts of times to check and see how the two are doing. A couple of times, Gary was being put in mortal danger by Patrick, but SpongeBob "thought" they were fine (laughing and having fun).
Later, Patrick attempts to give Gary a bath, though the latter, immune to water, strongly refuses. After this attempt fails, Patrick tries to give Gary a "bath" that involves the opposite of water: burning him alive with a flamethrower, but the next time SpongeBob calls, they are actually having fun, thanks to a flood that Patrick caused by spraying a running hose at him previoisly, but SpongeBob mistakes them for being in "danger."
SpongeBob quickly ends his grandmother's birthday and rushes home to see what the fuss is about, so he arrives home after a long, tiring run and sees that his house is destroyed and filled with water when he opens the door. He walks upstairs to the sound of Gary's meowing and sees Gary reading Snail Tails to Patrick. SpongeBob said how nice it was for Gary reading Patrick the book but Patrick said he thought the book was actually called "Meow, meow, meow." The episode ends after this.
This is the second time Gary stays with Patrick, the first was in "Dumped."
Apparently, SpongeBob has a storage room/pantry that hasn't appeared in any episodes before this one.
SpongeBob can be seen swimming in this episode and its sister episode, "Barnacle Face." Although, it was previously shown in "SpongeGuard on Duty" that he couldn't swim, it's possible that Larry's swimming training worked out.
Patrick wanted to dry Gary off with salt. If Patrick had used salt, he would've dried Gary up, while shriveling him up, and killing him, as salt is a dangerous thing for gastropods to come into contact with.
When Patrick sprays water on Gary with a hose, he says, "If you don't want to go to the bath, then the bath's coming to you." This is similar to SpongeBob in "Gary Takes a Bath," when he says, "If I can't bring you (Gary) to the bath, then I'll just have to bring the bath to you."
This is the second time "The Pineapple" was used as SpongeBob's address. The first time was "BlackJack."
This is the only time (excluding its sister episode) that realtime captioning is used. This is likely because they didn't have time to get offline captioning, but they still air the realtime captioning in reruns.
This is the second episode in which someone mistook Gary's name for Fred. The first was Squidward in "I Was a Teenage Gary."
When Patrick tries to clean Gary with a flamer, he burns SpongeBob's bed to ashes; but at the end of the episode, his bed is only destroyed in the flood and is seen again at the end of this episode.
