Sir Toothbrush VII is like all the Toothbrush Knights before him: extremely loyal and extremely brave. He is extremely loyal because night and day, and sometimes in between, he is there for Crazy Dave. He is extremely brave because he has to clean the leftover food and goo from the dark, deep, scary cave that is Crazy Dave's mouth. Because Toothbrush Knights use their bristles so frequently, they sadly wear out quickly. Luckily, Sir Toothbrush VII uses the Floss Lasso to help him in his fight.
