After King Bumi takes the chicken off Aang's plate shoving it into Sokka's mouth, Aang's plate continues to switch from having a clear plate to one with a piece of chicken on it.
The table the kids were eating at in the King's palace turns 90 degrees when they leave.
After Aang fights King Bumi, he is holding his staff upright. You can see that the number of dots at the top continues to switch from 1 to 2.
When Aang catches the chicken leg thrown at him by King Bumi, you can see a chicken leg already on his plate. But when Aang drops the caught chicken leg on his plate, the previous chicken leg is missing.
After Bumi frees Katara and Sokka from the creeping crystal, it's all over the floor. But when Bumi is telling Aang about Ozai, the pieces of crystal are gone.
During the battle between Bumi and Aang, for a split second the ring on Bumi's left ring finger turns green.
Sokka: Eh, how was Appa supposed to save us anyway?
Aang: Appa is a 10-ton flying bison. I'm sure he would figure something out.
Aang: I solved the question the same way I solved the challenges. As you said a long time ago, I had to open my brain to the possibilities. Bumi, you're a mad genius!
King Bumi: Oh, Aang. It's good to see you. You haven't changed a bit. Literally.
Aang: Name's Bonzu Pipinpadaloxicopolis... the Third, and these are my grandkids.
Katara: Hi, June Pipinpadaloxicopolis. Nice to meet you.
King Bumi: Aang, you have a difficult task ahead. The world has changed in the hundred years you've been gone. It's the duty of the Avatar to restore balance to the world by defeating Fire Lord Ozai. You have much to learn. You must master the four elements and confront the Fire Lord, and when you do, I hope you will think like a mad genius! And it looks like you're in good hands. You'll need your friends to help defeat the Fire Nation. (Momo lands on Aang's shoulder) And you'll need Momo, too!
King Bumi: Heheh! The people in my city have gotten fat from too many feasts, so I hope you like your chicken with no skin.
Aang: Thanks, but I don't eat meat.
Katara: Aang, do something, use your airbending.
Aang: Yeah, good idea, that will make us go even faster.
Aang (breaks through a window and out another window): Sorry!
Aang: The Earth Kingdom city of Omashu. I used to always come here to visit my friend Bumi.
Katara: Wow, we don't have cities like this in the South Pole.
Sokka: They have buildings here that don't melt.
King Bumi: Throw them... (Aang, Katara, and Sokka all gasp) ...a feast!
King Bumi: Who are you calling old? Okay, I'm old.
Cabbage Merchant (screaming): Off with their heads! One for each head of cabbage!
King Bumi: First Avatar, what do you think of my new outfit? I want your honest opinion... (random cough) I'm waiting...
Aang: I... guess it's fine...
King Bumi: Excellent, you've passed the first test.
King Bumi: Well, not one of the deadly tests. The real challenges are, uh, much more... challenging.
Aang: How am I supposed to know his name?
Katara: Think of the challenges, maybe there's some kind of clue.
Aang: Well, I had to think differently than I normally do.
Sokka: I know his name! It's Rocky!! Uhh...you know cause of all the rocks...
Katara: We're gonna keep trying, but that's a good backup.
King Bumi: I bet you like meat.
(shoves chicken leg into Sokka's mouth)
King Bumi: But for now, the guards will show you to your chamber.
Earthbender Soldier: My liege, do you mean the good chamber or the bad chamber.
King Bumi: The newly refurbished chamber.
Earthbender Soldier: Wait, umm, which one are we talking about?
King Bumi: The one that used to be the bad chamber, until the recent refurbishing, that is. Of course, we've been calling it the new chamber, but we really should number them. Uhh, take them to the refurbished chamber that was once bad!
Katara: Is it just me, or is this guy's crown a little crooked?
Cabbage Merchant: You're going to pay for this.
Aang: Two cabbages please.
Earthbender Soldier: Men, you'll be going off to combat soon. It's important that you be prepared for anything.
(Aang, Katara, and Sokka go by on an Omashu delivery cart.)
Aang (as Bonzu Pipinpadelopsocopolis III): My business is my business young man, and none of yours. I've got a mind to bend you over my knee and paddle your backside!
King Bumi: So tell me young bald one. Where are you from?
Aang: I'm from... Kangaroo Island.
King Bumi: Kangaroo Island, eh? I hear that place is really hoppin'... (A cough is heard, then Sokka breaks out laughing.)
Sokka: What? It was pretty funny.
Katara: You can't keep us here, let us leave!
King Bumi: Lettuce leaf?!

Character Debuts: King Bumi, Cabbage Merchant
Aang's final challenge, to guess the King's name, is very similar to the classic fairy tale Rumpelstiltskin, in which the main character must guess his name in order to save her son.
The Three challenges Aang faces are very simmilar to the 3 tasks Harry faces in Harry Potter and the Goblet of Fire.
Earthbending is based on the martial arts style called Hung Gar. A form of Kung Fu, Hung Gar uses many techniques, such as solid stances, that is used for earthbending. In addition, Hung Gar is the most pervasive form of Kung Fu, just like the Earth Kingdom is the largest and most populous nation.
The fact that the Cabbage Merchant is introduced in this episode could be a reference to the Lewis Carroll quotation "of cabbages and kings," from The Walrus And The Carpenter.

According to Avatar history, the Avatar is reincarnated. When Aang makes this remark, he also refers to most actual religions and beliefs that believe in the subject of reincarnation. In most of these beliefs, they do not eat most kinds of meat because, they believe that man can be reincarnated also into animals, and if worse came to worse, they could end up eating a family member that had been reincarnated into that animal before it's death.
