Pigpatch is a pink animatronic pig with light pink accents on his snout, inner ears, torso, and on the bottom of his feet. A pink belly button can be seen on his torso, as well a spiral tail on back of his buttocks. Similar to Happy Frog, Pigpatch has a different colored pelvis and upper legs, resembling actual pants. He has two short tusks from the bottom jaw and rosy red cheeks. He also has a right green eye and a left blue eye, referencing heterochromia iridum. Being the only Mediocre Melodies member to play an instrument, Pigpatch carries a brown banjo with tan accents.
Like the rest of the Melodies, he has an electrical power source box that activates him along with his fellow animatronics.
Based on his quotes in Ultimate Custom Night, Pigpatch tends to quote ancient proverbs and historical quotes by using the Japanese proverbs and the Sun Tzu quote, as he also inclined to play his banjo. His only non-historically inclined quote in-game suggests that he mocks his victims, even going as far as to consider their deaths to be dishonorable.

Pigpatch's name could be a reference to Porkpatch, another pig animatronic character, but much more imposing in appearance, that appears as a boss fought in FNaF World.
Pigpatch seems to be based on Jethro P. Hogg from Huckleberry Junction Playhouse Junction, who is also a pig animatronic playing a string instrument. The only difference between this connection is that Jethro P. Hogg played a guitar rather than a banjo.
Pigpatch’s head somewhat resembles the pink mask seen in the "Happiest Day" minigame of Five Nights at Freddy's 3, as other masks the children wear (not counting the original five characters from the first game) have eerie similarities with the animatronics of Mediocre Melodies with the exception of the blue mask.
Unlike the stereotypical pig, Pigpatch has three-toed feet instead of the usual cloven hooves.

From Pigpatch's catalog render, there is an error where his endoskeleton neck appears to be missing.
Ultimate Custom Night
Pigpatch appears in the Ultimate Custom Night demo troll game (a reskin of Doofas the Dinosaur) as one of the reskinned enemies.
Most of his quotes seem to reference ancient Japanese proverbs. One of them is a direct quote by Sun Tzu, author of "The Art of War". the literal meanings of the phrases may imply the failures of the player: "Even monkeys fall from trees", may be in reference to the player failing in general, since the phrase refers to the fact that even masters fail at their craft. "The nail that sticks out, gets hammered down." may be in reference to the player allegedly causing trouble, which in turn may be in reference to the Missing Children Incident, since the phrase refers to trouble-making. "The talented hawk hides his claws" refers to a talented person not bragging about their skills. However, the sense that Pigpatch used remains unknown.
Pigpatch appears in one of the cutscenes of The Toy Chica: High School Years as one of the students Toy Chica falls for. One of his ears is later seen stuffed in Toy Chica's bag along with the other animatronic student parts during the last cutscene.
