|Knucklehead's gender is not confirmed by Metro yet, so the gender given in the article is decided by the Dumb Ways to Die Wiki community.|
Knucklehead is a character seen in the Count to 10 mini-game.
He is very similar to Bonehead, as both of them are impatient with an angry face, and both have similar mini-games, both are hit by the train, and both are green. The only differences are that Bonehead doesn't have hair, and Knucklehead is seen without darker spots above his eyes.
- His hair's color code is the same as Boffo, although their hair style is different.
