The series is about different characters that represent various personalities, quirks, etc.; the idea is that they teach kids that it's okay to be different. Characters include (but are not limited to) a person with a chestnut for a head named Nut n' Nose, a guy with piano keys for teeth named Ken Bahn, a group of acorn kids called the Acorn Tots, and a person with a watering can for a head named Water Chap.
The setting of every episode is a white void containing nothing but a red door. A character comes out of the door and presents themselves to the viewers, and then finds themselves doing some kind of activity, with their quirk or personality often affecting how they do the activity. At the end of each episode, the character says good-bye to the viewer.
This work contains examples of:
- Alliterative Name:
- The name "Belly Boing" repeats the letter "B".
- The name "Klinki Klunki" repeats the letter "K".
- Amusing Injuries: Nut n' Nose accidentally whacks himself a few times when attempting to jump rope.
- Big Eater: Belly Boing will happily eat anything in sight without question, assuming he's able to get to it. In one episode, for example, he attempts to paint apples, but eats the apples before he can paint.
- Canine Companion: Mu Mu is Big Oggo's dog, who appears alongside him in any episode where he's the one who emerges from the door.
- Character Catchphrase: The Egg Prince's catchphrase is "That makes me boil!" when something makes him mad.
- Cool Old Lady: Grandma Fuji counts as this with her love of traditional Japanese culture.
- Exactly What It Says on the Tin: The Acorn Tots are acorn kids.
- Extremely Short Intro Sequence: The intro is only about three seconds long.
- Gentle Giant: Big Oggo is a giant, but given the nature of this show, it would only make sense that he's very friendly.
- Meaningful Name: Mu Mu the dog is named for the "mu mu!" sound he makes in place of normal barking.
- Non-Human Head:
- Klinki Klunki's head is a drinking glass filled with orange juice. He does anything to avoid the orange juice spilling out of his head.
- Water Chap has a watering can for a head.
- Obsessed with Food: Belly Boing's first thought when he goes through the door might as well be "Is there any food around here?", as he immediately goes toward any food he does find with the intention of eating and complains about being hungry if anything happens that makes him unable to eat the food, or if he realizes it isn't consumable.
- Open-Door Opening: Every episode begins with a character opening the red door and entering the room.
- Portable Hole: Disabear can toss his plates onto the ground and use them as holes.
- Ridiculously Cute Critter: A lot of the characters shown here are pretty adorable. It is a Japanese children's cartoon, after all.
- Shrinking Violet: Kaki Kaki is extremely shy and timid.
- Speech Impediment: Kaki Kaki often stutters when he speaks, which might be because of his extreme shyness and nervousness.
- Sweet Tooth: Belly Boing has an obsession with eating sweets.
- That Makes Me Feel Angry: If anything happens to the Egg Prince that makes him angry, he says "That makes me boil!" while his head boils like an egg to the point that the egg half of his head cracks a bit.
- Theme Tune Extended: The theme song is a mere three seconds long in the show itself, but an extended version
exists that's about two and a half minutes long. - Title Theme Tune: Erm, sort of. Given the short length of the episodes, about the closest thing to a theme song here is all of the characters popping out of the red door and singing the title of the show before going back into the door.
- White Void Room: The show's setting is one, being a completely featureless white backdrop containing literally nothing but a door.
- Your Size May Vary: Big Oggo is typically too large to walk out of the door, but just happens to be small enough to accompany the other characters when they sing the show's name at the beginning of the episodes.
