The Practical Pig

Practical Pig works on a new anti-wolf contraption, a lie detector, hoping to outsmart the Wolf's tricks. He engineers the machine to test truthfulness and to punish deception. He sets up the device as a safeguard for his brothers and the family, signaling a shift toward proactive defense.

Against Practical's warning about the Big Bad Wolf, the brothers sneak off to the pond for a swim. They underestimate the danger as the Wolf lurks nearby in disguise. The scene sets up the Wolf's later kidnapping.

The Wolf disguises himself as a mermaid to lure Fiddler and Fifer into danger. He captures the two pigs and brings them to the old windmill, where his wolf cubs await their dinner. The Wolf reveals his plan to eat the pigs only after he captures Practical.

While the Wolf plots, the Three Little Wolves begin plotting to trap the others and prepare to bake them. The Wolf aims to entrap Practical by sending a fake letter requesting help from his brothers. The ruse is designed to lure Practical away from home.

The Wolf heads out to capture Practical, leaving Practical's two brothers vulnerable at home. Meanwhile, the Three Little Wolves start to set their plan in motion by preparing to bake Fiddler and Fifer. The tension rises as the family braces for an attack.

As a messenger, the Wolf delivers the fake letter under Practical's door and blows his cover. Realizing the ruse, Practical becomes wary and prepares for a counter-move. The deception is uncovered just in time.

The Wolf tries to lure Practical into a trap, but the welcome mat opens and he falls into a pit. Practical captures the Wolf and straps him to a chair in the basement, turning on the lie detector. The device begins testing truthfulness, promising punishment for lies.

The Wolf denies knowing Practical's brothers and claims innocence, but the lie detector exposes the lies and punishes him with a mouth wash and a spanking. He fights back with evasive answers, but the machine keeps him honest and uncomfortable. The punishment underscores the device's power.

The Wolf tries a final lie, claiming he and Practical are pals, but the lie detector sees through it and administers more punishment. He endures the combined scolding, spanking, and mouth washing as the machine presses the point. The Wolf grows increasingly desperate.

Back at the wolves' hideout, the Three Little Wolves' baking scheme begins. One cub sprinkles pepper and the lid is knocked off, causing Fiddler and Fifer to sneeze violently. The crust falls apart and the pigs' plan is thwarted, trapping the wolf cubs instead.

With the crust ruined and the cookies spoiled, the two pigs break free from the trap and sprint back to Practical's house for safety. The escape feels urgent and chaotic. They warn Practical of the danger.

The lie detector pushes the Wolf until he admits the truth: 'They're in the old... the old mill.' The confession confirms where the brothers are held. Practical bristles with the plan to rescue them.

The Wolf is blasted out of the house with a firecracker and seemingly explodes in the sky. Practically, the danger appears to be resolved momentarily as the Wolf vanishes above. Practical begins to formulate a rescue plan.

The two pigs burst in, claiming they did not go swimming after all. The lie detector reacts instantly, flipping them over, dropping their shorts, and delivering spanking. The scene reinforces the device's unyielding scrutiny.

Practical tells his brothers 'Remember, this hurts me worse than it does you!' but the lie detector misinterprets this as a lie and spanks him too. The device punishes even the one who created it, adding a final moment of embarrassment.
