Alphablocks is a British CGI-animated children's educational television programme that tries to teach children how to spell with the use of animated blocks representing each letter. It is animated by Blue-Zoo and produced by Alphablocks Ltd. Once the Alphablocks discover that whenever they make a word it comes to life, many new adventures in Alphaland can be created. This is meant to help preschool children with learning the alphabet, spelling, reading and writing.
|A||7||Light and dark green||She likes to sing and help the other vowels. She has a plaster (Band-Aid) on her cheek and apples keep falling on her head. In "Prank" she discovered a red clown nose and played jokes on all of the other Alphablocks.|
|B||7||Light blue and red-orange||She plays the bass guitar and is D's younger sister.|
|C||7||Red and white with blue stars||The only letter who performs stunts. She wears goggles and makes cracks. She is K's younger sister. She often worries why she's even a letter because she makes the same sound as K.|
|D||8||Purple and bright green||He is a proper cube shape and he plays the drums. He is B's older brother. His catchphrase is "Don't despair".|
|E||4||Red||He is the busiest letter in the alphabet. His 'eh's echo from the megaphone he uses. He also becomes Magic E who is red with a top hat and a black ninja outfit to make the other vowels say their names. There is also Silent E. He has the same look as Magic E, but he does not wear a top hat. In "Sleep" all he wanted to do is to rest his sleepy head, but the other Alphablocks had other plans in mind.|
|F||4||Purple and white with orange visor||She is into floating and blowing. She is designed like an astronaut with a small life-support backpack. She can fly about in the air or in outer space. Her 'ffff' sound is used to represent the sound of a rocket-pack attached to her.|
|G||4||Green||She looks like a plant with flowers on her sides and grassy hair. Sometimes she drinks water, and when that happens her hair grows.|
|H||4||Yellow and red||She likes to run, but she can get tired when running. Her 'h-h-h-h' sound is panting.|
|I||5||Fuchsia||Her singing can be too loud sometimes but the Alphablocks really like her singing. She is also self-absorbed and thinks she is the most important letter (reflecting the use of 'I' to refer to oneself, or the first person).|
|J||4||Blue and white with orange 'beak'||She looks like a penguin, but thinks she is a jay bird. She thinks she can sing and fly like a real jay.|
|K||4||Yellow, with a green jersey and red pants||He likes to kick his football. He is C's older brother. Sometimes he fights with her because the hard C makes the same sound as K.|
|L||16||Lilac-pink with green socks||She loves to sing songs with her L sound. She sings a special lullaby to help the others get to sleep.|
|M||Unknown||White with blue feet||He is dressed up as a chef and likes to eat things (even things that are not food) which makes him quite greedy. This can annoy the other Alphablocks.|
|N||7||Vermilion||He is quite stubborn and negative. He says "No" even if he means yes and speaks with a thick Scottish accent. In "Ants", A, P, T, and S were blaming him for nothing, which made him very upset. In "Little Red N" he faced a challenge when the dog, the cat, and the pig refused to help him make bread out of wheat.|
|O||2||Orange||He does not speak, only being able to make his "oh" sound, but he likes to investigate lots of things with his magnifying glass.|
|P||14||Bright green, blue and purple with white stars and dark green pointed shoes||She can appear and disappear by making a popping noise and it can scare the others when they are busy. She appears to be a pixie. She is very sweet and loves to helps her friends.|
|Q||Unknown||Green with indigo hair||She is an old green woman who dresses like a queen and wants to be quite quarrelling. She is also in love with U which is who she also needs to make her "qu" or "q" sound, but he always runs away.|
|R||12||Red and black||She looks like a pirate (reflecting the stereotypical "arrrrrr" pirate exclamation), and she has a tomboy personality.|
|S||10||Red, white, blue, orange, green, and yellow||She resembles a beach ball. She can inflate and deflate and fly about. In "Clap" she became depressed when she questioned her status as a letter, because she makes the same sound as soft C.|
|T||Unknown||Navy blue||He wears a monocle and has a white moustache. He really likes drinking tea. He says "t, t" when he is out of tea. He is one of the consonants who appears a lot. (In fact, he is the second-busiest Alphablock in Alphaland.) He refers to his name as "Tea".|
|U||9||Light blue with purple shoes||He wears square glasses and is quite moody. He always runs away from Q (probably because she wants to be quite quarrelling). He usually say words like "unfair" or "unbelievable".|
|V||Unknown||Red and white||He is a racing driver who is very fast with his steering wheel and has feathers on his arms. His 'v-v-v' sound is his "vroom".|
|W||3||Dark blue||He cries when he gets hurt or when he is upset, causing floods everywhere. His 'w-w-w' sound is wailing. He refers to his name as his sound.|
|X||Unknown||Gold and blue with white socks and red cape||He is a superhero called The Exciting X who has X-ray vision. He becomes Plusman if his letter shape goes all wonky, turning it into a plus sign by accident, and he turns red with a different personality. He then has the power to make compound words - putting two words together into one. In "Plusman", he shows how he became Plusman with his laser by rotating his X the same way his letter shape did and made the compound word 'lunchbox'.|
|Y||1||Yellow||He is the youngest Alphablock after O and the only consonant who can make a semivowel sound (see Series 1, Episode 4). He perseveres even if he has trouble doing things.|
|Z||Unknown||Lime green with silver-white beard||He is the oldest Alphablock with a walking stick (cane) and can sleep almost anywhere (reflecting the "zzz" sound commonly used to represent the sound of sleeping or snoring in comic books).|
