Natterjack is a green toad who hosts the first two quiz rounds of Kerwhizz.
His questions often involve reconising pictures, with activities including:
- What is the silhouette?
- Which puzzle piece is missing?
- What outfit matches Natterjack's?
- What is the other half of the painting?
Natterjack occasionally appears during the race, where he tries to direct the teams along the right path. The teams often ignore him, leading them to have problems and/or reach a dead end.
- He is the only character to present two questions during the quiz.
