Blacktooth is a fictional pirate that Grandpa Dave made up in the Arthur episode "The Big Dig". He is a parody of Blackbeard.


Blacktooth was an anthropomorphic aardvark dressed in a stereotypical pirate outfit, with a tan-colored collared shirt, brown vest, and a black tricorner hat with a skull and crossbones symbol on it.


According to Grandpa Dave's story, Blacktooth was very wealthy; in fact, he had so much treasure on his ship that its weight was starting to sink it. In order to get around this problem, he decided to bury all of his treasure at the nearest port, which happened to be Elwood City. He drew a map for himself to find find the treasure later on, but that was 20 years before his return, so he was never able to recover his treasure.
