Disney Animators often use caricatures of friends and colleagues to style specific characters. Following that tradition, Tangled directors Nathan Greno and Byron Howard, inspired two of the Snuggly Duckling Tavern thugs. At the bottom right is Thug #1, resembling Nathan Greno. Holding on to Flynn's right arm is Thug #2, inspired by Byron Howard. In addition to their likenesses, Greno and Howard also provided the character voices.
