A related manga series written and illustrated by Botan Hanayashiki under the name "BH Snow+Clinic" was also released. Originally serialized in Dragon Junior, the individual chapters were published in three tankōbon volumes by Kadokawa Shoten.
The story is based around 11-year-old Saga Bergman, a young girl in a small German town called Muhlenberg (based on real town of Rothenburg ob der Tauber). Saga lives with her grandmother Regina and works in a coffee shop when not in school. Saga is extremely structured and plans her life down to the minute. One day, she notices a tiny creature in a fluffy outfit that appears to be starving. She offers it a waffle, which helps revive the tiny creature. Saga learns that this tiny creature is Sugar, an apprentice season fairy. Sugar explains that season fairies alter the weather by playing a magical musical instrument, and her specialty is snow, which she creates by playing the piccolo. Sugar is joined by two more apprentice season fairies, Salt, an outgoing male fairy who plays the trumpet to make the sun shine more brightly, and Pepper, a quiet and caring female fairy who plays the harp to make the wind blow. All three apprentices are shocked at the realization that Saga can see them, since humans are not supposed to be able to see season fairies. Pepper speculates that exceptional humans might be able to see them, which is the best possible explanation. Sugar tells Saga that the three have been sent to Earth to train as full-fledged season fairies, and to do that, they must find 'Twinkles'. Sugar moves into Saga's bedroom and sets up residence, much to the consternation of the super-structured Saga. Saga is a well-meaning, intelligent and highly organized girl who feels compelled to look after the childish, loud and irresponsible Sugar, who is incapable of looking after herself. The story is complicated further with the arrival of three adult season fairies—Turmeric, a cloud fairy; Ginger, a rain fairy; and the Elder, the leader of the season fairies—and two more apprentices—Cinnamon, a hail fairy, and Basil, a thunder fairy. With the highly disruptive presence of Sugar, Saga's life goes haywire. Her friends Norma and Anne think that she is losing her mind, and her teacher, Miss Hanna, is worried that her best student is acting strangely. Not at all concerned with her strange behavior is Greta, an egotistical rich girl who considers Saga to be her rival, and Phil, a goofy inventor who keeps trying to persuade Saga to help him with his experiments, if he is not already busy building and trying out his latest device.
The initial concept for A Little Snow Fairy Sugar began with the producers at TBS deciding that they wanted to have a series about a little fairy. Haruka Aoi took this idea and came up with the concept of a fantasy town where Season Faries lived and traveled the world to control the weather. Together Aoi, Yasunori Yamada who was responsible for the series structure, a representative from Kadokawa Shoten, and series director Shinichiro Kimura the final framework for the series was hammered out.
Kimura focused on telling a story that focuses on the relationship between Sugar and Saga, while not fully explaining some things to viewers. In particular, he notes that the series never really explains what the "Twinkles" are that they faeries are searching for because he felt viewers should draw their own conclusions and that the show's purpose to show how friendships are formed and how they result in people growing as human beings. The character of Sugar started as with the basic idea that the main character of the series would be a snow fairy. When trying to think of a name, Yamada associated snow with white, which he said reminded him of "sugar", giving the snow fairy its name. With that name decided, he decided that all of the other fairies would also have the names of condiments. Initially, the story was going to be set in the fairy world, with no humans at all, however, as they worked on fleshing out the story, the character of Saga was introduced. Aoi originally envisioned her as a quiet and calm girl, but she was eventually changed into the more assertive and organization obsessed character seen in the final version. Yamada notes that Kimura was responsible for turning the story into a more positive and cheerful one than the original concept might have resulted in. Yamada felt the character of Greta was a key character, particularly towards the series. He notes that he and other staff members adored her as they felt she was a "good girl and a lovable character". Aoi was initially surprised to find that Sugar ended up being more tomboyish than he had originally planned, but after watching the completed series, he decided that it made her cute. He felt the completed series was a "great mixture of scenario, characters, music, background and voice acting."
The visual designs for the characters began with conceptual designs by Koge-Donbo. As the series was an original work and not based on a manga, she was unsure on what the final appearances for the characters would be like. Character designer Keiko Kawashima notes that this made it confusing for him to follow the designs at first. He initially designed Saga with a more youthful appearance, but in discussing the character with Kimura, it was decided that she should have a more mature appearance that would be clearly distinctive from the appearances of the fairies. In animating the series, full-digital animation is used. Because of the fairies smaller size and movements, they would initially be drawn the same size as humans, then shrunk down when needed for scenes with humans. This allowed the animators to give the characters more detailed and realistic movements.
In designing the setting for the series, art director Shichiro Kobayashi was sent to Germany to search for locations. Though initially reluctant to go, as he felt reference materials would be enough, Kobayashi notes that it ended up being a valuable experience as he was able to better capture the Europeans' aesthetic sense and the "tastefulness" that permeates the towns and houses. Returning to Japan, he attempted to capture the "atmosphere" of the region, using pastel colors and aiming to make the art feel "comfortable."
The series music began with Pioneer requesting that it be romantic feeling, using piano and strings, which pleased music director Nobuyoshi Mitsumune, who had been working with the medium in his previous project. Wanting to also do something different, Mitsumune initially considered using elements from the rock and dance genres, but after seeing the conceptual art and reading the series scripts, he revisited his vision and decided to go with something more orthodox that better matched the inspiration he felt from the series. For the vocal tracks, sound director Yota Tsuruoka notes that the most difficult issue was dealing with the scenes where the faeries and humans would be having separate, unrelated conversations at the same time. He decided not to just have the tracks recorded separately for combining in the editing stage, but instead had the voice actors actually perform the scenes as written, with each group doing their conversations at the same time just as it occurs on screen.
