The annual 4th of July Picnic is two days away and decorations are going up in Deering Oaks Park. As Nate and Sludge stroll along, they run into their friend Pip and his parrot Prattles. Pip explains that he’s lost his other parrot—Penelope—a drone that he disguised as a parrot, as a friend for Prattles. Pip plans to sing the Star-Spangled Banner with Prattles and Penelope at the picnic so they don’t have much time.The next day, Claude comes calling and asks Nate if he can help solve a case for him.  He explains he’s lost Baxter, his drone parrot. A lightbulb goes off in Nate’s head--an idea that may very well lead to solving both cases at once.What happens next is a mix-up of epic proportions, but in the end Nate’s smart thinking and problem-solving makes sense of it all. And on picnic day, Pip is able to sing his song with Prattles and Penelope, however a pig called Anastasia manages to somehow steal the show!
