According to Greg Heffley, he is nice enough, but Greg doesn't think he can get past the fact that Tyson pulls his pants all the way down when he goes to the urinal. In The Ugly Truth, when Greg Heffley is at the Lock-In and is playing Guess Who?, his Team takes a picture of Tyson's bent arm. Mr. Tanner mistakes it for a picture of somebody's rear end. However, Mr. Tanner finds it a mistake when Tyson matches the picture with his arm, this was because his elbow had a mole which saved them from punishment.
