Slappy Squirrel awakens to find that her tree house is now "The Christmas Tree" at "Rockyfellow" Center. Then, in "Punchline: Part I," Chicken Boo and several other characters address the eternal question: "Why did the chicken cross the road?" Later, Katie Ka-Boom has been invited to the prom, but gets angry while arguing with her parents over her curfew and what to buy in "Prom Night." And in the finale, "Punchline: Part II," another eternal question is addressed: "Which came first: the chicken or the egg?"
