The Heffleys' Pig
|The Heffleys' Pig|
The Heffleys' Pig is a baby pig owned by the Heffley Family, first introduced in Diary of a Wimpy Kid: The Long Haul. It seems that he is only fond of Manny, just like how Sweetie is only fond of Susan and Gramma. The pig is the second farm animal won by the Heffleys after a goat (mentioned in Diary of a Wimpy Kid: Cabin Fever) which was won by Greg for correctly guessing a goat's weight, but Frank didn't let them keep it, just like that case, Frank didn't want to keep the pig but Susan said she couldn't return him because the pig "imprinted" on Manny. Rodrick also agreed to keep the pig as he thought you could get bacon from him every morning the way you get eggs from a chicken. As of The Meltdown, the pig has run away after being sent to obedience school by Frank, and no longer lives with the Heffleys.
The Long Haul
The Heffleys won the pig in the Highway 1 Country Fair for guessing the weight of a grown hog correctly. The baby pig was originally going to be returned since Susan Heffley only entered the contest for fun. But the crowd was insulted, and wouldn't take no for an answer, which made her change her mind. The baby pig would eventually "imprint" on Manny.
The pig caused trouble for the Heffleys. They tried to bring him into the second hotel they stayed at by hiding him in the cooler. While there, he caused a mess in one of the bathrooms, and ate all the food in both of the minibars. Later, while in the van, he woke up and caused chaos, which resulted in Greg getting bit by the pig. Because of all that, Susan put the pig in a petting zoo. Manny was heartbroken by the news, while the Heffleys took Greg to a vet to check Greg's bitten finger. The Heffleys came back for the pig later, when they where aided by two Spanish men. At home, Susan managed to teach him some tricks.
Greg says that Susan Heffley would reward the pig with a cookie every time he stood on his hind legs. Since then, the pig had learned to walk on his back legs and never walks on all four hooves. Greg then talks about how he doesn't wear collars or leashes because he thinks he is too good for them, also pointing out how he didn't know how the pig had managed to do it without thumbs. The pig is able to walk into the open world to the content of his heart, with the addition that he does not have a curfew, unlike Greg. It is possible that the pig might have learned to write, as Greg seemingly gets a letter from the pig during his trip to Hardscrabble Farms. However, this could have been a prank set by one of the family members.
Greg said that the pig figured out how to use the See-and-Talk and can make him say almost full sentences. After Greg finishes his chores, he decides to help himself to a piece of candy corn, which he won in a contest. He comes up into his room to discover that the pig had eaten all of the candy corn, and found a way to open it. At first, Greg is angry with the pig, but when it started looking sick, Greg worries and calls Rodrick to help him. Rodrick tries to drive the pig to the vet, but before they get there, the pig throws up in the van. Since it was Greg's fault that the pig threw up, Rodrick makes Greg clean up the mess. He tries, but is totally grossed out by the vomit, that he throws up himself. Unfortunately, the a lady raking the leaves witnessed the whole thing and calls the cops. Greg explains to the cops what happened. When Rodrick and Greg finally starts driving, Susan catches them, and as punishment, Greg has to take three chores out of the Grab Bag. The pig is later seen eating gummy worms when Greg tries to film a movie.
After the pig getting mad about not going on the Heffleys' vacation to Isla de Corales during The Getaway, Frank sends it to obedience school, but the next day Frank gets a call from the person who runs the place saying that the pig had ESCAPED. Greg's family puts up posters to find it, but is unsuccessful. At the end of the book, Greg says he bets the pig is somewhere warm, having the time of his life.
The pig is surprisingly super smart. He somehow opened three cans of soda, can use the TV remote to watch television with Manny and was able to remove his GPS collar soon after being put on him, despite not having fingers. That makes Greg feel annoyed. The pig also can walk on two legs, refuses to wear a leash, and eats at the dinner table. The pig also occasionally wears a pair of Manny's shorts which Manny put on him.

- According to Greg, the pig is a male.
- He is a domesticated pig as he is from a livestock of a farm.
- The name of the pig is currently unknown, it is also unknown if he has been named or not.
- He wears shorts as revealed in Old School. However he does not wear it in Double Down.
- He eats at the dinner table, to Greg's disapproval.
- For a while after Susan taught him to walk on two legs, he went through a phase of only walking like that. However, in Double Down, he goes back to walking on all fours.
- In Cabin Fever, Greg won a goat in a similar competition but Frank refused to take the goat as his pet. This can be explained because the fair people let them not keep the goat but didn't let them not keep the pig.
- He might be able to write letters as seen on page 172 of Diary of a Wimpy Kid: Old School when Greg talks about his mail, though this is most likely a prank from Rodrick.
- He doesn't wear leashes or collars because he supposedly thinks he is too good for them. Furthermore, he is capable of taking a leash off of him despite lacking thumbs.
- There are no instances of Greg talking about or even introducing the pig to his best friend Rowley. In Diary of a Wimpy Kid: Old School Greg calls him to his house to inform him about his lemonade selling plan, and they were inside the house for a while because of the heat; but there was no incident of Rowley with the pig.
- Out of all the characters introduced, the pig seems to be the most personified as pigs cannot learn how to walk on their hind legs, due to their bone structure, similar to that of dogs (there has only been one pig in the history of the world who currently resides in China who can walk on his front legs) and pigs cannot write for obvious reasons, however the writing part was probably a prank.
- He once wore a collar but in about 5 minutes he threw it out.
- The pig appears to be super smart since he can walk on two feet, can use the T.V. remote, can remove his G.P.S. collar despite not having fingers, supposedly thinks he is too good for leashes and wears a pair of Manny's pants given to him from Manny. It is also possible the pig can write as shown on Page 172 of Diary of a Wimpy Kid: Old School. The pig also learned to use Manny‘s potty as shown in the book Diary of a Wimpy Kid: The Long Haul when he goes to the bathroom despite no explanation that he's been trained too.
- The pig's ascend to being human-like may be a reference to Animal Farm, as near the ending of the novella, the pigs do the same to the fact that they cannot be distinguished from a human.
- This is not very unusual because pigs are actually intelligent animals.
- His name might be "Junior" according to a twitter post by the series author, Jeff Kinney. He explained that the pigs name might really be named "Junior" in the series Spanish translation. The twitter post is here.
- The pig did not appear in Diary of a Wimpy Kid: The Getaway. However, he did appear in The Meltdown, but only in a flashback—it's explained in the previous book, that the family left the pig in a kennel while they were on vacation. He got angry when they came back and he ran away.
- The Pig made an appearance in a Happy Meal Commercial created McDonald's along side with Greg Rodrick, Gammie, and Sweetie.
- The Pig's drawing can be seen as a sign named "All yeh can eat buffet" in the Corny's restaurant.
- It's unknown if the pig will appear in any future installments of the series, due to him running away.
- It is revealed by Jeff Kinney that the pig is a replacement for Sweetie because Jeff wanted to keep Sweetie around more. However, Sweetie still makes cameos.
- The Heffleys' Pig is seen in multiple scenes in the preview of Diary of a Wimpy Kid: The Long Haul (film)
