Professor Curio, an elderly archaeologist in Cappy Town, runs a struggling antique shop and museum preserving relics from ancient Dream Land and the forgotten Cappy civilization. His institution battles chronic underfunding and recurring vandalism, demanding tireless repairs. Desperate to revive public fascination with history, he fabricates artifacts to falsely link King Dedede to royal ancestry—a risky gambit coerced by the monarch’s financial threats.

Pear-shaped with a yellowish-peach complexion, he wears a green shirt, orange bow tie, and grey spiky hair framing his bald crown. A bushy grey mustache obscures his mouth, complemented by equally thick eyebrows.

Socially reserved and prone to stammering, Curio speaks with clinical precision, avoiding conflict yet bonding with villagers through shared tasks. He mentors Tiff, who respects his expertise and aids him during crises. His scholarly pursuits yield scant income, mirroring the town’s apathy toward preservation.

Though pragmatic enough to collude with Dedede for survival, Curio staunchly condemns selling artifacts for profit, clashing with mercenary interests. His principles fray when his museum faces destruction—monster raids, rowdy locals, or stray livestock—exposing raw frustration.

Central narratives explore his exposure of Dedede’s historical frauds and reckoning with his own forgeries, balancing his role as history’s custodian against ethical compromises forged in desperation.
