Laying aside existential questions about Bobby Bumps being the Antichrist, here's an Earl Hurd cartoon about Bobby and how he came to acquire his dog -- and get in a lot of trouble. Although primitively written and animated by the standards of a later era, it's an amusing collection of scrapes and scraps the two get into.
Hand-drawn animation was always the most expensive sort of film-making, since it required skilled artists working hard on 1440 individual frame for every minute of screen time. For many years Hurd, and J. R. Bray controlled several patents that helped to keep the costs down. In this one, we can see one technique that must have saved a mint: partial animation. During the studio era from about 1930-1955, full animation was in use, although character design became simpler to save on costs. While this one is not at the level of Clutch Cargo or the 1960s Marvel series, it's severely limited.
