S23·E5 Without a Voice

Geoffrey, George and Bungle are getting ready for a boat trip across the river, but Zippy's not very well and has lost his voice, so they all decide to go on a pretend boat trip instead. Zippy pretends to be the captain of the boat, but as he can't speak Geoffrey gives the orders for him. Bungle pretends to swim in the water and then they get shipwrecked on a desert island. Everyone has a picnic and then Geoffrey reads a story called 'Chirp Finds His Voice'. Geoffrey gives Zippy some medicine and then he falls asleep.
