Cartwright also found them to be “kind of disgusting looking", likening them to "overcooked hot dogs.” The actress typically improvised and performed the role without a written script, borrowing direction from the character's emotions during particular scenes that vary from excited to sad. Cartwright voiced Rufus while voicing Chuckie Finster from Rugrats. Cartwright reprised her voice role in the show's 2019 live-action film adaptation, having hoped Disney would invite her back once the project was announced. Cartwright considers Rufus the film's only truly animated aspect, hoping that the character's inclusion "adds this little extra thing that inspires kids."

Actor Sean Giambrone, who plays Ron in the film, expressed admiration for Cartwright's "ability to bring Rufus to life with her voice", feeling that he bonded with the character despite being unable to see or interact with him while filming.

Before deciding on CGI, the filmmakers had also considered depicting Rufus using puppets before ultimately determining that computer animation was "the only way to capture his expressiveness ... We really worked hard with the animators to make him feel real, because we didn’t want a Roger Rabbit situation going on
