While Charlie and Marv play a game called "Squidbones", Lola thinks it sounds like arguing, and is convinced that Charlie and Marv are not friends anymore. Later, after writing a letter that says "From Charlie", Charlie explains that he was just playing "Squidbones" with Marv, and they weren't arguing after all.
