Ah yes, the Amazon arc, and here I had thought the Hitler Youth Groups were a thing of the past. *remembers the little boy doing the Dai-Shocker salute*
What's more is that the treasure Trixie tries to get in each world is a kiss on the lips from a boy or girl in the world she's in, although she considers the kiss she took from Twilight to be her "Greatest Treasure in the Multiverse".
Tomoda Yuri and Ogami Takumi from Faiz's World
Detective Yashiro from Agito's World
Mayu from Kabuto's World
Trivia: Mayu's foot popped back when Trixie kissed her. :3
