"in a pineapple under the sea with his starfish friend Patrick."
SpongeBob is friends with Patrick, and SpongeBob does live in a pineapple under the sea, but he does not live in that pineapple with his starfish friend Patrick. Rachel already thanked @Morani_Bonner for correcting our mistake, which was actually my mistake and for which I'm sorry.
It turns out our audience has many SpongeBob SquarePants experts, perhaps none more expert than newly 6-year-old Hunter, who exclaimed as he watched the show last week that we'd gotten it wrong about SpongeBob. And now Hunter has sent us a diagram of SpongeBob SquarePants' neighborhood, so that we might never get it wrong again.
Hunter, thank you. Thank you for spotting the error in our report. Thank you for the picture. And thank you for having faith that facts will win.
P.S. To everyone who wrote in to say that it's not SpongeBob SquarePants' neighborhood, that too was my fault. Hunter just sent the picture. I added the part about the neighborhood. Also, SpongeBob has a pet snail named Gary the Snail, and depending on how you feel about pet sovereignty and snails, you might think he doesn't live alone. Now I'm retiring retreating to Bikini Bottom, or wherever.
