Hopadiah "Hop Pop" Plantar is a supporting character in Amphibia, voiced by Bill Farmer (Goofy). He is the traditional and over-protective grandfather of Sprig Plantar and Polly Plantar. Though he shares a brave heart and will stick with his family through thick and thin, he also inadvertently inspired rebellion against the Toads of Toad Tower. He also possesses knowledge of the Calamity Box, the relic that stranded Anne Boonchuy and her friends to his world, hiding it from plain sight without Anne knowing fearing it could be dangerous.
Role in the series
Hop Pop is roped into the crazy adventures of the Shell Lodge Squad and Trista Hylander when Hank Jr takes over the toad warriors and by extension Amphibia in Hank Jr's Revenge, becoming a regular aid when he learns of his home's true origins from The Bestiary Dimension, the same original home of the monsters of Mewni.
