The Piglings

The Piglings are 10 likely adolescent pigs who work for King Pig and try to stop the birds as they try to stop him. They're usually bosses there to add diversity so you're not battling King Pig all the time. It is suspected they are King Pig's kids, as many sources throughout the Creeperverse say this, but King Pig Jr. is cited as being King Pig's only son (and kid). All the Creeperverse sources are not on close terms with anybody affiliated with King Pig or wouldn't have the actual knowledge, and just assume they're his kids based on logic and other people telling them this. If you were playing the game, you would assume that they're his kids based on the evidence, just like the NPCs, but no actual legitimate canon source says they're his kids, and really, none of them even say who they really are.

History
The Piglings first appear as fanon bosses for any game that appeared in Creeper's head sometime in early 2014 or late 2013 (I remember because the school year). They also appeared on paper that year, and expierienced great design changes, and names were given to them in 2016. Their history is longer than listed, because this history section only covers their appearance in the Creeperverse rather than overall. They had never appeared in any game until the Creeperverse was started, and were just planned to replace bosses in previous games. Their abilities change throughout their history and games they appear in.

Angry Birds Go! Piggy Island Derby
They first appear in Angry Birds Go! Piggy Island Derby (ABG: PID) as non-playable characters in the final race of different cups. The first one you battle is Keiser in Keiser's Lab Parkway. You start off driving on an average parkway with trees and grass on the side. Soon, it starts to rain, and it turns to night. A few flashes of lightning, and then shocking mines that appear in all of Keisers' labs' designs are rained onto the ground. Later, a drone starts firing at players, and then Keiser appears at the front and starts shocking people who are directly in front of him. (This is expanded in the Keiser article)

The next one is Lennon, battled in Trappy Terrace, consecutively after Keiser. All Lennon does is hover in the top left corner and occasionally make Mashboar-triggering tripwires or spike holes covered with thin leaves, or bear traps on the track. Mostly, there are traps there beforehand (This is expanded in the Lennon article)

The next one is Trig in the Anger-to-Anger Gauntlet track. For the first lap, it's a fairly normal track, but on the second one, Trig comes in and starts trying to charge at you. He will follow you around, then lock in to you, and take 3 seconds to charge. You can drive away from him while he's charging up. If you're playing multiplayer, he will, somehow, charge at both of you. For this reason, you can't play this track online. He will then, around the time of the third lab, breathe fireballs in a random pattern along the area, then charge, then fireballs or a smash that will trigger a small earthquake. (This is expanded in the Trig article)

Next is Roxanne's Roundabout, a looping track that's dark and death-like. It's gloomy, and is the only boss track in Piggy Island Derby where the boss doesn't appear, and it's just a hard track. Rifles will fire on the walls when you drive by them, and nooses will fall down in areas around you, and you hope not to get caught. Sometimes, it goes dark and you can't see anything. Hamster Ball Pigs scatter the track.

Fifth is Music Museum versus Melissa. There are Trumporks on the sides that blast sound on you, and jumping tunes to deal damage. Parts of the track are made of piano keys, some black and white (like usual), but some are red, and that will hurt you. The track is a bit different, you go the first lap, and the second one afterward, but there is a loop at the end. In the loop, you fight Melissa, who waves her baton to deal damage. Angel Trumporks will swoop down on you and blast music into your face.

Angry Birds: The Journey Past Piggy Island
They each appear as different bosses in this game, battled in the order they are listed in the infobox, each with their own attacks. This is the first time they are formally introduced, since a few of their names are not revealed in Piggy Island Derby. How or why they are here remains unclear, but they are there, and they will battle you. The first time you battle them is in Feral Forest - Wild Woods Warfare where you fight Courtney. It's a fairly easy fight, but it gets harder as you go along. In every location, they are there to stop you from getting to the next place, logically to prevent you from returning to Piggy Island (the plot of the game). Why they don't want you to return remains a mystery as well.

Angry Birds: Return to Tomorrow
They appear as bosses in this game, with different abilities, each expanded on in their own pages.

Birth Order
The entirety of the birth order has never been confirmed, but there is a few bits of it that have been. For starters, Jason and Mason are confirmed twins. They both have a similar physical appearance, and are battled together frequently, unlike the other Piglings which are typically battled seperately. This is not to say Mason and Jason are not battled seperately. Courtney is supposed to be one of the oldest, since she was young during Mudbeard's rule. Smoothcheeks has been on the throne for a relatively long time, so it would make sense Courtney is older. However, this can spark some confusion, since if the Piglings really are King Pig's kids, King Pig would have to have been born, and fairly old when he made Courtney, and as far as the movies go, Smoothcheeks doesn't exist yet, and the movie would at least cite Coutney to be Leonard's granddaughter. However, Mudbeard is a bit selfish, and it would make sense for his granddaughter to be his assistant. Ross is no longer his assistant, and we don't know why this is, so it could be assumed that when Courtney turned the right age, he kicked Ross, and now she's the new assistant. But, this is all from the viewpoint that these are Smoothcheeks' kids, which has not been confirmed, therefore, this could still make sense. The movies have also been deemed non-canon, in the Creeperverse at least. That tangent aside, Courtney is one of the oldest, along with Mason and Jason, who are likely in the age of college judging by their attitude, physique, and expirience. Keiser is the youngest. This was confirmed in a dialogue from Angry Birds: The Journey Past Piggy Island, before you battle Keiser. When the zeppelin zooms in, Keiser starts talking: "Ha! You have only beaten the others as dimwitted as they may be!" (In this scene, Trig's face reddens) "But you should know that my genius is no match for you!" "As the youngest, I'm treated harshly, but it's time you (he points to you, then turns around lazily) and you (he turns back toward you and assumes his manical appearance) know the true wrath of intelligence, especially against those who lack it!" (The battle ensues). In this speech, Keiser tells you that he is the youngest. This was to later be confirmed by Pyrocreeper Games and Rovio when asked about. Keiser is, quote, "Cited as a source who would know information about the Piglings. Therefore, inside knowledge about the Piglings that he utters is true, unless proven otherwise later on." So, Keiser is the youngest. Lennon is the second youngest, according to the descriptions in the scrapbook of Angry Birds: Return to Tomorrow, quote, "The second-youngest Pigling, Lennon enjoys causing trouble with big traps, plans, and trickery! He sometimes uses this to cause trouble amongst his siblings, especially Keiser. He is still one to watch out for, don't let that playful personality fool you, or else you may fall into one of his spiky traps or get tricked into blowing a mine!"

Appearance
They first appear in Angry Birds: The Journey Past Piggy Island, although, in the Creeperverse timeline, they first appear in Angry Birds: Return to Tomorrow in time periods before the events of AB: TJPPI. They appear in all in-game illustrations as past pigs, not like that of the movie, even in their 3D forms. However, they look different from the average pig, in order to show that they are not just normal minion pigs. They each have their own features which are discussed in the appearance section of their articles.

They all ride on a big zeppelin that has a big carriage, with a smaller carriage attatched to the blimp, that they ride in to the boss fight arena before talking/fighting you. The zeppelin is gray with a symbol that is a green outline of King Pig. The carriage is made of rope, and they're all placed in different areas of the zeppelin.

Aside from the appearance on the boss rink, they are not seen often. In the final battle against King Pig in Return to Tomorrow, they can be seen in their zeppelin cheering from the sidelines for King Pig to win. In The Journey Past Piggy Island, they appear at the very end, all defeated. Then, Courtney walks off the beat-up zeppelin they're dazed in front of, and falls flat face-first, knocked out, with a white surrender pennant sticking up. Their other appearance is in Angry Birds Go! Piggy Island Derby (see section). They are involved in the cutscenes in Bomb's Rescue. (The cutscene features will be added when Bomb's Rescue becomes a main project)

When one of them is getting ready to fight you, a smaller carriage (appearing and enetering in different ways depending on the Pigling) pulls up in front of the zeppelin, and the boss you're fighting jumps in, then you proceed with the battle
