Continuity mistake: When Porky sets up the easel after arriving at the forest, he puts on the ground a box and some paint brushes. But when we see a long shot of Porky painting, the box and paint brushes have gone.
Continuity mistake: When Porky is displaying the enormous fish he has caught, Daffy comes along and asks him if he has a fishing licence. The fishing line and bell vanish before the shot changes.
Audio problem: When Daffy says "So long, Rembrandt!" whilst pretending to ride on a bicycle, his beak doesn't move.
