It’s not just Nintendo who filed trademarks in Japan. Other game companies such as Bandai Namco also apply for their own trademarks from time to time. The company’s recent applications for several trademarks may imply that something from Klonoa fans may soon appear.
Bandai Namco has applied for trademarks for “Waffuu Encore” and “1&2 Encore”. The term “Encore” is often used for remake games released by Bandai Namco in Japan. As for “Waffuu”, that is Klonoa’s slogan, and Klonoa is the protagonist of the series of the same name. Both of these trademarks may imply that remakes of Klonoa: Door to Phantomile and Klonoa 2: Lunatea’s Veil may be coming soon.
