This Unnameable Little Broom (1985)

A red-clothed puppet lives in a room with a missing wall. He rides a tricycle. Gadgets surround him. He eats dandelion tufts. A painting lies on a table in the middle of his room. He hides. A bird-man flies into the room curious about the vaguely erotic painting. Something in it moves: the bird-man looks closely, the painting clamps shut, he's ensnared. Trike-man emerges from hiding, frees a cricket from inside the table and throws the cricket into the night. He pulls a bolt of cloth through a hole in one wall, yard by yard. Trapped in the cloth is the bird-man, whose wings the trike-man clips; he cages the bird-man in his table and rides his trike maniacally around the cage.
