Ribert and Robert's Wonderworld is a children's education animated/live-action hybrid television series that was created by Mike DeVitto.
The series revolves around Ribert, a young animated toad that wears a cap and later a safety helmet, who wants to know "everything", and Robert, his human friend, as they spend each episode learning about different topics against the backdrop of a magical island amusement park, known as Wonderworld.
He pilots the roller coaster car that Ribert and the viewers (known as Power Pals) ride as they learn about the day's topic.
The goal of each episode is to solve three "challenges" as the roller coaster car travels the track in the Wonderworld amusement park.
The series was distributed in the United States by American Public Television to over 90 local PBS stations.
