Manny Heffley's imaginary friends are made-up friends, that were made-up by Manny which include, but aren't limited to, Johnny Cheddar, Danny, Petey, Charles Tribble, The Other Charles Tribble, Joey, and Tiny Jim. They appear in The Third Wheel.
It is unknown if Manny treats his imaginary friends as actual friends, but he uses them to get extra dessert and blames them for causing trouble to avoid punishment. Manny once had a meltdown because his mother supposedly left Charles Tribble at the frozen foods aisle. He made Susan drive back to pick him up.
Susan told Greg that Manny could be traumatized if he learns that his imaginary friends are not real, so they had to go along with it. Greg hopes Manny grows out of having his imaginary friends soon, as he thinks that they are a big burden to the rest of the family, one example being that he has to wait for them to finish using the bathroom before he can.
Trivia[]
- They haven't been mentioned since their debut, which possibly implies that Manny has outgrown them likely due to his friendship with Mikey in the following book.
