It's a fat kid's dying dream as he slowly dies of dabeties in a children's hospitalThis would explain EVERYTHING about this batshit insane show.
The pilot episode is really the last episode.Remember when Chowder and Panini have been mercilessly Flanderized? Well, that's because one can consider them to be the last episode in which there is a resolution to both Chowder's classification as a scatterbrain and the Will They or Won't They? of Panini X Chowder. Therefore, the so-called Flanderization of both characters were really intended from the beginning, and the pilot is just aired as the first episode, and takes place much later in the series.
The Brain Grub episode is the first episode.This episode acts as though the characters aren't aware of the fact that they aren't in a show. If we take this as the first episode, then all the other lampshade hangings and such make sense in every other episode.
Mung was the one that left Endive behind at her wedding.It's been stated more than a few times over the course of the show that Mung loves the ladies (and continues to do so, even after being married to Truffles for god-knows how long.) It's also been stated that he hates doing things by the book. What started out as a possible full-fledged romance between him and Endive basically turned to rot after he found that he couldn't stand her textbook-perfect nature; that, coupled with the fear of giving up his bachelor lifestyle, caused him to get cold feet and run off on his own until he met Truffles, who didn't give a crap about how he worked or who he flirted with on the side. Also, before anyone mentions the "Mung and Truffles have been married for 450 years!" bit, keep in mind that Endive's age isn't even hinted at yet, meaning that she could be as old as he is...
The entire series is All Just a Dream, a dream induced by Chowder getting food poisoning.Because that would explain the Negative Continuity, the bizarre colors, people, and cars, the surrealness of the episode plots, and Chowder's obsession with eating.
gazpacho is secretly a pirate.that's why he hates ninjas
Alternatively, the whole series is the hallucination of a mental patient.You said it. The entire city is extremely surreal, and nothing seems to logically make sense.
Before entering puberty, the species which Chowder and Panini belong to are in a state of...what's a nice way to put this....
Alternatively, the species Chowder and Panini belong to are of the tanuki.
Chowder is the true idealized form of Instrumentality
Marzipan City really is made out of marzipan.Because if you can mold it into tiny little intricate shapes, then heck, why not an entire city where almost everything revolves around food?
Chowder's Cute Little Fang is the same as his "Wisdom Tooth"
Chowder takes place in the same universe as Katamari Damacy
Schnitzel is actually a Pokémon.
Chowder is Light Yagami
Marzipan City is built upon Candied IslandWhen Knuckles and Flapjack finally find it, Flapjack and Chowder will start the eating contest to end all eating contests!
Chowder's world is the fairytale world in the far futureOur time to be exact. It's a different world or universe or whatever but it does make sense. Mung is probably an elf and Endive an ogre. It also explains why there are cat/bear/rabbit hybrids. If there are half humans in fairy tales, then why not hybrids of other things?
Male rock monsters are rumored to be very well equippedThis is why so many elderly Marzipan City ladies are hitting on Schnitzel (no, it's not just Endive - See "The Big Hat Biddies""). The reason why Schnitzel took a job where he always gets stuck with all the menial labor, is that his only other option was to become a gigolo, and that was beneath his dignity.
Chowder has Asperger's Syndrome or some form of autismIt would explain his tendency to blurt out random things without thinking about what he's saying, and his social awkwardness. In an early episode it is also implied that he's dyslexic, which is a common symptom of autism.
The theme song is an in-universe commercial for Mung's restaurantThis might be a pretty obvious WMG, but the song's all about cooking and food, the lyrics are sung by Mung and the gang as an invitation for people to "stay awhile 'cause something's always cooking", and it ends with the characters chattering to each other about how well they thought the song went. It gives the impression that the theme song's really an in-universe commercial they're putting together for the catering company.
Chowder is a girlNo one else knows, and Chowder doesn't realize they don't know. That's why (s)he's horrified at Panini's advances and why (s)he frequently enjoys wearing girl's clothing. This is also why (s)he never hooked up with Marmalade, despite being very compatible with her...not to mention the whole purple clothes thing.
Marmalade is the child of Kermit and PiggyGazpacho did call her a "Pig Frog Girl"
Marzipan City is hell, or at least in hell.Everyone in the city committed one of the Seven Deadly Sins, and for their punishment have been warped into bizarre, animal-like forms, had their sins exaggerated to the point of absurdity, and put into an illogical city that sometimes seems to be actively trying to hurt them.
The original Schnitzel died in the episode "Chowder's Catering Company" and was replaced by Schnitzy, his twin.At the end of Chowder's Catering Company, Schnitzel jumps in a barrel and rolls into the Wonderhole in which, according to Chowder, nobody can ever get out of. He was replaced by Schnitzy, his exact twin, who performed at the comedy club Gazpacho also peformed at in "Gazpacho Stands Up". However, Mung and Chowder fail to beleive that original Schnitzel is still trapped in the pit.
Chowder has an eating disorderWhy else would Chowder eat EVERYTHING and ANYTHING he comes into contact with (occasionally residents of Marzipan City)?
The world of Chowder will be completely overrun by his and Panini's children.They will not be able to keep that whole "no more babies" agreement in the the finale and will keep on making babies until their descendants have out-competed everyone else.
Chowder is a distant relative of Eek! The CatJust compare the two. Although probably not immediate family (Chowder being a hybrid creature), the two do bare more than a passing resemblence to each other.
Gazpacho's mother was dead.Gazpacho's tendencies on always saying "mother always says" is a mean to cope of her loss. He even went as far as to dress up as her so that no one would know.
Chowder takes place in the same world as TorikoBoth Marzipan City and the whole world of Toriko are food obsessed, and the quality of food is directly dependent on how hard it is to obtain the ingredients and prepare them into an edible form.
Ceviche is biologically femaleA kid FtM.
Chowder's parents are around.In the episode "The Deadly Maze", during Gumbo's flashback of when he quit being Mung's apprentice, Mung says "Well, we lost another one. Shintzel, get the apprentice catalog!" So in Chowder's world, or at least Marzipan City, its common for kids to be send off to the apprentice delivery. Chowder's parents were poor and want their son to have a better life. They have him put among the other chef apprentices since he likes food, a lot. Off-screen, Chowder writes to his parents about his many adventures.
Chowder is MarxNo, seriously. Something about Chowder terrified me as a kid. I couldn't figure it out though until now. [[kirby.wikia.com/wiki/Marx Look at how much he looks like Marx]]! The alternative is that Panini is Marx.
Ceviche moved away or died in the future of "Chowder grows up".Maybe the reason why he didn't show up was maybe he became extremely popular so he moved to a different country or he saw how happy chowder and panini were married so he became depressed to the point of suicide or got killed in some accident whatever you think makes sense.
