Chowder: (looking around inside his mouth) What is this wonderful place? Whoa! It's a big cave that smells like feet!
Taste Bud #1: Sweet! Sweet!
Chowder: No, I said "feet."
Taste Bud #1: Sweet!
Taste Bud #2: Sweet!
Chowder: Feet.
Taste Bud #1: Sweet!
Taste Bud #2: Sweet!
Chowder: Feet aren't sweet unless you had feet made out of caramel. Then I guess they'd be sweet. I wish I had feet made out of caramel.
Taste Bud #1: Sweet!
Taste Bud #2: Sweet!
Chowder: You guys are weirdos. Can't you say anything beside sweet?
Both Taste Buds: (seeing a Puckerberry demon sneaking up behind Chowder) Sour! Sour! Sour! Sour!
Chowder: See? That's better. (edit) Truffles: (to the Elemelons) It sure is hard to be a strong-willed woman, you have opinions, and they lock you in a cage. (edit) (Chowder thinks to himself and the voices say)
Taste Bud: Sour! Sour!
Mung: A good chef always knows how to balance sour and sweet.
Truffles: Did you pee on the seat? (edit) Chowder: Why are you guys always so grumpy? Sometimes I get grumpy when I'm hungry.
Frank the Sour Guard: Quiet!
Chowder: Shnitzel's usually grumpy, but I think that's 'cause he has to make a poo. Maybe you had to make a poo.
Frank the Sour Guard: be quiet!!
Chowder: Sheesh! Grumpy. (edit) Truffles: I am not scary. (eats food and spits it out) This food. Now that's scary! (edit) Chowder: (to Truffles) You're... you're... SCARY...! (edit) Chowder: When everything is sour
Like before you take a shower
And your stinky from your head down to your feet
There is one thing that'll save you
And it's when you bring your face to
A big bowl of something really sweet
Oh, we're sweet,
and, we're sweet as can be,
oh, we're the sweetest sweeties of them all
Oh, we're sweet,
got it tattooed on my seat.
So, your empire of sour must fall.
When, you feel your lips pucker,
when, your suckin on a sucker
Then there's way too much sourness in your life
So, why not be a honey,
with ears like a bunny
and sweeten up the dull and sour wife?
Oh, we're sweet.
We're as sweet and can be
Oh, we're the sweetest sweeties of them all,
Oh, we're sweet
Wisdom Tooth: And dang gum, their pretty neat!
Sour Ron: And, my empire of sourness falls down...! (edit) Chowder: You all need to take a poo! (edit) Truffles: What is that racket?!
(a giant tennis racquet with arms and legs leaves the scene) (edit) Wisdom Tooth: Now, I know what your thinking. Well, stop it, and pay attention to the story. Sickos. (edit) Wisdom Tooth: And so Chowder and the enslaved taste buds marched toward what seem like certain doom. Well, maybe not certain doom. More like doom with a strong possibility. Possibiladoom. (edit) Chowder: How did you get up in the sky?
Wisdom Tooth: Kid, I'm gonna spell this out nice and slow-like. You... you still with me... are the only one who can stop these angry sour guys from taking over your mouth.
Frank the Sour Guy: Move your round pink butts!
Chowder: How am I supposed to do that? I'm an eater, not a fighter.
Wisdom Tooth: I don't know. But you don't on it pronto, you aren't gonna have a mouth to eat with anymore.
Chowder: No mouth? (edit) Chowder: (to his wisdom tooth) Hey! I know you. Can I have some cheese, Mr. Moon?
Wisdom Tooth: I ain't the sassin' frassin' moon, you picklehead! I'm your wisdom tooth!
Chowder: My wisdom tooth? (edit) Mung: Come on, man! Put your legs into it! We gotta pull Chowder out of his mouth!
Shnitzel: Radda radda radda!
Mung: I'm not making you do all the work! I'm standing here pointing at the pucker hole, aren't I?!
(The pucker hole sucks Mung's clothes off)
Shnitzel: (disgusted) Aw, radda! (edit) Truffles: I don't make nice!
Mung: You better start learning, woman! (edit) Chowder: (talking about his sweet tooth) That was my favorite tooth! (edit) Wisdom Tooth: This story is about a man. Well, not so much as a man but, a boy. Well, not an actual boy but, as a cat...bear, rabbit thing. So, here's a cat-bear-rabbit thing. You know what? Let's say he's a boy, makes things easier. This here's a story about a boy, a boy... (coughs badly) Sorry about that. That would come to save us in our darkest hour. (edit) Truffles: Yeah, baby, let's bring on the crazy! (edit) Chowder: Hey, Truffles, I brought you dinner.
Truffles: LET ME OUT!
Chowder: Aaaaaah!! (edit) Truffles: You silly fruits are going down! (edit) Chowder: Don't be scared, we're only going to squish you! (edit) Chowder: How do you think that makes me feel?
Taste Bud: Bitter!
Chowder: Darn tootin'! (edit)

Mung Daal's elemelons were named Queenie, Princess and Duchess. (edit) The minimum age to have a wisdom tooth is 15. In The Puckerberry Overlords, Chowder has a wisdom tooth, and he is not yet 15 years old. (edit) According to the series, every character was named after food, but in this episode, there were a few characters that aren't named after food. (edit) Truffles mentioned that she was a "mushroom pixie".
(edit) The book one of the elemelons was reading was actually the "pickle in a cup" recipe book from the Burple Nurples episode. (edit)

Character Name: Sour Ron

When the Puckerberry ruler says his name, Sour Ron, it is a reference to the Lord of the Rings evil character named Sauron. (edit) On the first TV movie of Foster's Home for Imaginary Friends, House of Bloos, when Bloo tries to figure out the name for Duchess, he says Queenie and Princess, just like the names for the Elemelons. (edit) Puckerberrys is also a berry in the Disney original animated series, Dave the Barbarian. (edit) Chowder: I'm an eater, not a fighter!

This is similar to Foster's Home for Imaginary Friends Edwardo's line, "I'm a lover, not a fighter." (edit) In the book, Mung is reading while handling the Puckerberry reads "Peligro", which is Spanish for "Danger". (edit) The elemelons are a parody of both watermelons and elephants. (edit)
