Snork recurs throughout the Moomin anime continuity as Snorkmaiden's brother. He takes life very seriously, exhibiting a personality marked by pomposity and bossiness, traits his sister occasionally punctures. He approaches tasks methodically, preferring systematic solutions and demonstrating a strong inclination for organization. This is evident in his meticulous notes kept in exercise books with lines precisely spaced one inch apart. He enjoys being in charge and displays leadership tendencies.

Within the anime series, his role expands considerably beyond his minor presence in the original books, portraying him specifically as a scientist and inventor. His storyline centers on an obsession with flight and aerial technology. He designs and constructs two distinct flying ships. The first falls victim to sabotage and is destroyed. Undeterred, Snork persists in his work and ultimately completes a second flying ship. This dedication culminates in his departure from Moominvalley aboard his finished aircraft at the series' conclusion, a final act driven by his ambitions.
