When the wind-up robot Quinn made malfunctions and runs amok through 3rd and Bird, it is up to Samuel, Rudy and Muffin to stop it.

Muffin introduces the community to her new friend, Ben the pig. Samuel and Rudy warn Muffin that pigs are messy and lazy, but when Ben turns out to be clean, kind and helpful, the birds quickly change their tune.

The community builds a beautiful barn for Ben to live in, but he informs them that he is only visiting the tree. Ben sings a heartfelt farewell to the community before parachuting down to the ground.
