for I'm a Manatee by John Lithgow and Ard Hoyt
As a little boy falls asleep, his pet guinea pig's water bottle begins to leak, filling the room with water, and the boy imagines himself to be a manatee. So begins this ocean adventure. The score to the song is provided, along with a CD of Lithgow singing the song and an instrumental track. Full color.
