Most of the stories involve discovering magical objects and creatures, adventures in different locations or dealing with everyday situations.

[3] After great success of the series, a sequel called Delightful Moomin Family: Adventure Diary[b] was produced and aired on TV Tokyo from October 10, 1991, to March 26, 1992.

The original series also spawned a theatrical prequel film Comet in Moominland which is based on the second novel of the same name and video games releases.

The series was dubbed into many languages (including, but not limited to, the aforementioned English, Swedish, Finnish, Norwegian, Dutch and Danish) and aired worldwide.

Moomin, along with Little My, Moominpappa, and Moominmamma, wake up in Moominhouse, while Snufkin also comes back from his south travel on the first day of spring.

During the story, Moomin and his friends find out the magical silk hat, that turns out to belong to the Hobgoblin.

After Thingummy and Bob return Moominmamma's missing handbag, the Moomins celebrate the event with a large junket, where suddenly the Hobgoblin also arrives.

At the end of the series, Snork decides to go on a journey with his finished flying ship while Alicia and her grandmother also leave the Moominvalley for the third winter period.

The series concludes when the winter arrives, the Moomins fall into hibernation and Snufkin travels to the south once again.

Before the production, author Tove Jansson was already displeased with the previous Moomin anime adaptation from 1969 due to how unfaithful the series' characters and stories were to her original source material.

A year later in Tokyo, Livson showed a small preview of the anime series for both Tove and Lars Jansson.

Hiroshi Saitō and Masayuki Kojima were the series' main directors while Akira Miyazaki did the screenplay for the first 12 and many later episodes.

Certain events and characters from the books and comic strips are missing to fit the series' own continuity or for reasons unknown.

Generally Finland-Swedish actors are always cast as the Moomins in Swedish productions and localizations because Tove Jansson herself was a Finland-Swede.

During the early 1990s, the first anime series has also been dubbed into British English for Children's BBC (later renamed as CBBC) in the United Kingdom under the title Moomin.

The full voice cast includes Susan Sheridan, Toni Barry, Pat Starr, Peter Whitman, John Chancer, David Graham, Garrick Hagon, Jeff Harding and Stacey Jefferson.

[3] Despite the different opening and ending themes, Hawaii airings featured the British dub from Children's BBC.

The sequel series does not feature any adaptations of Jansson's books but some of its episodes were based on Moomin comic strips.

The sequel series has been aired for example in Tove Jansson's home country Finland (but only in Finnish dub), Israel, Latin America, Norway and Poland.

Producer Dennis Livson was later highly critical towards the sequel series and stated that "we had nothing left to mine from by way of Tove’s own stories.
