Dirk Tufftooth is a bulldog who appears in Boom Blox and Boom Blox Bash Party.


He is gray with a red collar that has spikes on it. He has an underbite, his canines stick out over his upper lip.


He throws baseballs at anyone passing by. He could be considered the enemy of Buckley Beaverton, because he is the second most standard character and will throw balls at him, attempting to destroy him. He could also be the enemy of Buster Maguff, because he is a good dog and Dirk is a bad dog.
