Penny, the Engineering Tail of the Fourth Pig

Penny, the fourth little pig, is called to the scene of the wolf-huffed-and-puffed-damaged homes of her brothers, the Three Little Pigs. Together the four of them rig up traps for the threatened return of the Big Bad Wolf. Successful in driving off the wolf, the four design and build a home for them all.

Lesson learned: Science triumphs. And humor, especially pig puns, are highly appreciated.
