Funny Moments: SpongeBob's attempts at removing the barnacle off of Pearl's face are nothing short of amusing.
Jerkass Woobie: You do feel bad for Pearl here. While she acts temperamental, she also places great emphasis on how others perceive her, earning some sympathy in the process.
Squick: Some people found the barnacle to be very gross to look at, especially when it's leaking.
Pet Sitter Pat
Catharsis Factor: For those familiar with "Gary Takes a Bath", Patrick soaking Gary with suds and water can be seen as much-needed karma for Gary’s behavior in that episode.
Character Rerailment: In contrast to his behavior in "A Pal for Gary", SpongeBob is more likable because of how much genuine care he has for Gary, and isn't completely oblivious to what's going on around him.
The Woobie: Gary is definitely sympathetic since he who has to put up with Patrick's Lethal Stupidity in this episode. SpongeBob is also sympathetic because of how much he worries for Gary.
