Donald Duck & Co #37/1993

In "Musen," Mikke og Langbein find themselves stranded on the Trans-Siberian Railway after sabotage derails their train near Lake Baikal. With the journey halted, they encounter a mysterious amphibious creature who believes humans are poisoning the lake—a claim that puts them in the middle of a growing environmental mystery. Written by Harald Dyrkorn and illustrated by César Ferioli, with inks by Angeles Felices, the story unfolds with quiet tension and a touch of whimsy, all captured in a striking cover by Tello Art.
