Professor Curio

Prof. Curio (Mr. Curio in Japan) runs an antique shop/museum where he displays his artifacts of ancient Dreamland and Cappy civilization. (The place is almost constantly being trashed so he spends a lot of time piecing it all back together.) Unlocking the past is his hobby, and he has the honor of being one of the more intelligent Cappies. He'd do nearly anything to get funding for his research though... including placing fake artifacts in the ground to prove that the Dedede clan have been around for generations.

Trivia

 * His name comes from the Latin root meaning 'inquisitiveness.'
