Let's get started with creating the pigs for the Angry Birds game:

1. The pigs are created in a manner similar to that of the the wood planks. Start by creating an empty GameObject and naming it Pig.
2. Next, create a plane, make it a child of the Pig object, and remove its Mesh Collider component. We do this because of the rotation the plane will need to face the camera. Being a child of the empty GameObject allows us to ignore that rotation when working with the pig.
