Since then, like all other characters on the show, Butters has been animated with computer software, though he is portrayed to give the impression that the show still utilizes its original technique. In the tradition of the show's animation style, Butters is composed of simple geometrical shapes and colors. He is not offered the same free range of motion associated with hand-drawn characters; his character is mostly shown from only one angle, and his movements are animated in an intentionally jerky fashion.

Prior to making his first major appearance in the season 3 episode "Two Guys Naked in a Hot Tub", crew members referred to the character as "Puff Puff" and "Swanson", the latter name which he was identified as in the season 2 episode "Conjoined Fetus Lady", and would continue to be addressed by the two names in storyboards and scripts until it was finalized as "Butters" in the aforementioned "Two Guys Naked in a Hot Tub". Butters gradually became one of Parker and Stone's favorite characters, and for the show's season five finale they created the episode "Butters' Very
