Innovating the only way they know how: accidentally.
A pig is sticking boxes together. Then he goes back and suddenly, he accidentally step on the wrench and fall down a cliff into a big box of tools. Then a robot (consisting of the pig in a crate for the core, a hammer for the right hand, a powered screwdriver for the left, crates for the feet, and springs connecting the limbs to the core) comes out of the box. The three other pigs next to the box stare in awe and surprise. But then the robot (which shall be referred to as "Porkatron", hence the title,) accidentally fell forward while walking. So the pigs have an idea: Porkatron will help them with their work. So Porkatron has helped them in whacking blocks (with the hammer), screwing nails (with the screw), and even using himself to make a bridge for the pigs to go through. After passing the bridge, the three pigs have an another idea. So they take out the glue, stick the boxes together and make another robot as the Porkatron's sidekick!
