Leon

Leon was a minor character who appeared in “The Whimsical World of Leopold”; his only appearance was in “The Mouse Whisperer”.

Appearance
Leon was a young mouse with dull grayish-brown hair, gray eyes and a black nose and matching whiskers; he was wearing a slate gray button-down shirt in addition to a matching pair of breeches and a pair of black boots, respectively.

After his death sent him to the Purgatory, he gained a blue tongue.

Personality
Leon was a lonely kid who had no friends growing up, so he made one for himself, in the form of a Nevelyashka-esque doll, whom he named “Neville”.

However, despite his loneliness, he was a happy-go-lucky boy who, along with Neville, would spend much of his time climbing trees, even though he always got in trouble everytime.

During his time in the Purgatory, he was among the first to befriend Mitya.

Death
In the early autumn of 1922, Leon became bedridden for days after he contracted tuberculosis; in late autumn, he eventually passed away from tuberculosis with Neville by his side, after which he took the doll with him to the Purgatory.
