Insights

Released in 1982 and now retired, Maximillian Mouse is an early Fabuland set tied to a named character with a distinctive molded figure, and surviving sealed copies are scarce which has supported post-retirement appreciation, while niche demand and limited liquidity temper upside.

Set Facts

The set contains a Fabuland Figure, Maximillian Mouse and a car that is blue and orange.

About Fabuland

The Fabuland theme included sets that depicted the land of Fabuland and introduced Fabuland Figures, characters with human-like bodies with various animal heads. Fabuland was the first LEGO theme to introduce named characters that focused around a story and was the first LEGO theme to feature licensed products such as storybooks, playing cards, children’s clothing and animated TV series to enhance the playing experience through storytelling and role play. The FABULAND figures have heads of a mammal, a reptile or a bird sometimes topped by a peaked hat, and arms and legs with motion very similar to LEGO minifigures.

Summary

Fabuland Maximillian Mouse set 3781 was released in March 1982, retailing for $6, but has since been retired. New, unopened Maximillian Mouse sets are valued at $75, while used sets can be found for $9 in good condition.

Great adventures for small children. Stories to build, play and collect. Small children have a strong urge to make up worlds of their own. The animal figures make it easy for children to act out exciting stories. Large pieces make building quick and easy, and story books in the model sets tell delightful tales for children to build.
