The Hatch - Burdette shows Smooch and Winslow the shell of the egg she hatched from and asks them where their eggshells are. Thinking that they have lost them, the monkeys search the World Tree for their shells, learning about fish, frog, and turtle eggs along the way. Finally, Snook takes them to Madge's, where they find out that mammals aren't hatched from shells, but born, so they didn't lose anything after all! Sounds of the Forest - Wartz moves into a new log, but after his first day there he is exhausted - he keeps hearing mysterious whistling and knocking noises and he can't sleep. Madge explains that wind passing over holes in the log is causing the whistling, and later Wartz discovers the source of the knocking - it's Winslow who's preparing to give a concert with the new instrument he has made.
