Johnny Cheddar is one of Manny's imaginary friends in The Third Wheel. He is the most recognizable of all of them by far. He causes trouble, being "the troublemaker of the pack", and supposedly is to blame for Manny's mistakes. He likes to relax and apparently breaks dishes. Once, after having broken a dish, he got a time out on the brand-new recliner in the living room. However, Greg started thinking that he might have been the one who stole his towel at the end of the book, however this is not likely since he is not real, it is likely somebody else from the family stole it or Greg misplaced it.
