The Angry Beavers (1997)

S04E02 Three Dag Nite!

Dag stumbles upon an Easy-Clone oven at a yard sale, which brings a chuckle from Norb, who knows the gadget only produces silly plastic replicas. Ignoring the instructions in his eagerness, Dag quickly finds himself overwhelmed when a flood of duplicate Dags clogs the dam, leaving Norb to manage the chaos.
