Plank

Plank is a character from the Disney Junior special Sofia the First: The Floating Palace, voiced by Phil Morris.

Like King Triton, he hates humans and believes they're evil because Merroway Cove was once attacked by humans; many merfolk were hurt, including him evident by the scar on his left arm. He is the chief adviser of Queen Emmaline, and vehemently advises she wields her trident to sink any human vessels that comes to Merroway Cove.
