Minor
Lucy Big (voiced by Abigail Daniels) is a kind-hearted 8-year-old girl who lives with her parents in the Big (normal) World. Lucy, along with her mum (Mrs Big), her dad (Mr Big) and her teacher, Miss Cookie are the only big people who know about the Little Kingdom.
Miss Jolly (voiced by Kate Robbins) is a snail riding teacher and a pet trainer. She also has a snail called Trigger.
Trigger is Miss Jolly's pet snail.
Redbeard the Elf Pirate (Nigel) (voiced by David Rintoul) is the pirate uncle of Barnaby Elf and also the son of the Wise Old Elf. He is introduced in series 1, episode 31, where it is also revealed that his real name is Nigel. He sails the oceans in a pirate ship named Pedro, though his size prevents him from engaging in acts of actual piracy, and he is more of a treasure hunter and explorer. He is quite smitten with Nanny Plum whom he considers his sweetheart, however, Nanny Plum seems to have little interest in him romantically but deep down, Nanny Plum loves him back. He has a pet parrot, Polly, although she is normal-sized and barely fits inside Redbeard's ship. He is the same voice actor acting as Granddad Dog on Peppa Pig.
Mrs Fig (voiced by Morwenna Banks) is the Scottish-accented teacher of Mrs Fig's Magic School. Nanny Plum used to go there and Holly and her friends went there when they were old enough. Despite being a fairy, she detests magic and says the most important rules of magic are "Don't use magic" and "Magic should only be used for serious things". As a result, the Wise Old Elf likes her as they have similar views on magic. Mrs Fig loathes Nanny Plum, who is implied to have been her worst student as she does not adhere to Mrs Fig's ideas on magic. Morwenna is the same voice actor acting as Mummy Pig and Madam Gazelle on Peppa Pig.
Mrs Fotheringill (voiced by Morwenna Banks) is Daisy and Poppy's playgroup teacher. She was at one point sent back in time to the age of the dinosaurs by the children from her playgroup. She seems to be American due to her accent and when she calls Gaston a "ladybug" (an American term for a coccinellid) as well as mistaking his gender. She is presumably an elf, although her ears are hidden under her bob, and she has never been seen blowing her horn.
Mr Gnome (voiced by David Graham) is a gnome that often wanders around the Little Kingdom ever since Nanny Plum magicked him into the Little Kingdom to guard the golf course from moles. He later occurred to be a lazy, slightly talkative, and gluttonous annoyance to the entire kingdom. After his debut appearance, whenever characters find him, they scream in horror, "Ah! The Gnome!" accompanied by either a timpani or bass drum soundtrack representing the characters' fear.
Gloria Gnome (voiced by Judy Flynn) is Mr Gnome's "girlfriend". She was introduced in the episode, "Springtime".
King and Queen Marigold (voiced by John Sparkes and Morwenna Banks) are the king and queen of a kingdom far from the Little Kingdom. They are often described as "snooty" characters who likely mock the Thistle family's misfortunes, such as judging the Little Castle by calling it a "shady-old" castle. But when the Thistle family's plans tarnish and most of the castle is demolished, the Marigolds unexpectedly find the castle's remnants "modern" and "daring" instead of teasing them as Queen Thistle predicted. The Marigolds are a cheerful, happy-go-lucky and slightly a snooty satire of high-brow trends in modern art and fashion. Queen Marigold is Queen Thistle's older sister, technically making the Marigolds part of the Thistle family and the uncle and aunt of Holly, Daisy, and Poppy. Their castle appears to be based on Saint Basil's Cathedral in Moscow.
"Granny" Millicent Thistle is King Thistle's mother and Victor's wife. She often believes in using strong and dangerous magic and becomes a bad influence on Daisy and Poppy when she teaches them how to do it and giving them the wands of their great-grandparents (much to her son and daughter-in-law's chagrin), henceforth referencing how some grandparents spoil their grandchildren. She revealed that The Wise Old Elf used to love magic, right before the Monkey's Kittens incident. She lives with Victor in a castle high in the clouds.
"Grandpapa" Victor Thistle (voiced by Alexander Armstrong) is King Thistle's father and Milicent's husband. He is "extremely bonkers" and along with his wife, also believes in using wacky and dangerous magic. He, Milicent, and the Wise Old Elf (who they refer to by his real name, Cedric), attended the same college, and like Milicent, even spoiled Daisy and Poppy in his last appearance in the episode "Journey to the Centre of the Earth" by taking them on a trip to a volcano.
Mrs Witch is a witch who lives in a small cottage in the Little Kingdom. Although one time Holly wanted to know if she was evil, she apparently appears a nice witch who only gets angry or inflicts curses (like turning Nanny Plum into stone) when insulted (mainly as a retaliation or comeuppance), especially as she's touchy about her private cat, Moggy.
Captain Squid (voiced by Andy Hamilton) is also a pirate, along with Redbeard the Elf Pirate. He is Redbeard's brother and also the Wise Old Elf's son.
Barnaby Elf (voiced by Stanley Nickless) is a cheerful, loud, talkative, and giggly friend of Ben and Holly. He is Redbeard the Elf Pirate's nephew and also the Wise Old Elf's grandson. He has the same voice actor as Pedro Pony from Peppa Pig.
Strawberry (voiced by Zara Siddiqi) is a fairy who is friends with Holly and often attends lessons with her. She is very cheerful, happy-go-lucky, bubbly, and silly, and has her red hair styled in a small tulip bun. Her mother is the vet of the Little Kingdom.
Violet (voiced by Julia Lucy Moss) is one of Holly’s friends. She has pink hair styled into pigtails.
Fleur (voiced by Alice May) is a calm, quiet, and shy friend of Holly and attends school with the other fairy children (most of them were female for an unspecified reason). She sometimes got turned into a cat by Daisy and Poppy and when she played a game where she was the antagonist, Holly was the "damsel in distress/victim", and Ben was the hero by being a "knight in shining armour", she forgot to magic away the tower and her witch's outfit when her mum called her for dinner.
The Fairy Mayor (voiced by Alexander Armstrong) is a character based on Boris Johnson, the former mayor of London and former prime minister of the United Kingdom. He is Strawberry's dad. He does not like "big people" because they always step on fairies and elves.
Zyros (voiced by Bram Karek) is an alien that lives on Planet Bong. He gets offended when he is called a baby, he likes magic jelly and he has a fear of big people. According to him, he and the other aliens get smaller as they get older.
Ben's Robot (voiced by either Richard Ridings or David Graham) is a robot that Gaston found broken in the middle of the meadow with no key.
