Klonoa appears in Bandai Namco’s promotional 2022 calendar.
The page in question is Children’s Day (こどもの日, Kodomo no Hi) themed; a holiday celebrated on the 5th of May in Japan. The art was drawn by series character designer Yoshihiko Arai.
Previously, Klonoa made an appearance in the company’s 2020 calendar.
Another look at the Bandai Namco 2020 calendar that features Klonoa on the January page. It appears to be a promotional item. It is worth mentioning that one of the pages features Mr. Driller artwork, which was recently trademarked along with Klonoa and other Namco series to possibly be receiving “Encore” game releases.
Edit: On the January page, the Prince from the Katamari series and one of the characters from the Kotoba no Puzzle: Mojipittan series appears as well. Katamari having received an Encore (or Rerolled overseas) title in 2018 and Mojipittan receiving one Spring 2020. Their appearance is either coincidence or on purpose.
