This clip comes from Private Pluto, a Walt Disney cartoon short released in 1943 starring Pluto, where exaggerated sound design was used to sell every gag. The flexitone, a small handheld instrument with a flexible metal strip, gave animators a warbling, spring-like voice for stretching, slipping and snapping movements. Later, Hollywood Edge catalogued similar cartoon effects for reuse in television and film, which helped these short, elastic sounds survive long after the original short. Editors still reach for them because they instantly signal old-school cartoon comedy in less than a second.
