Adventures in Dinosaur City, or, Dinosaurs the Movie (Video, 1991)

You can watch it here.

Ignore the content warning; it applies to at least one of the other movies in the list below the video.

Fatty Finn (Video, 1980)

Australian film based on the now-obscure Australian comic strip. You can watch it here, and you can watch the 1927 silent film this film was loosely based on here.

Robot in the Family (Video, 1993)

The famously befuddling direct-to-VHS outsider-art family film seen on Too Many Tapes and Red Letter Media. You can watch it here, and read info from the film's creator and the robot's actor (and info about the real-life inspiration for the villain) here.
