The Squirrels are excited to learn that Mr Wobbly, the jelly juggler, is coming to town, and they can't wait to see him. When they become impatient, Duggee explains to them that the week will fly by and that there's lots to be done in that time.

The Squirrels notice that Happy looks and seems different. He is frowning, his smile is upside down, and he's wearing new trainers. When they check in on him, Happy is frustrated, but he can't seem to identify where his frustration is coming from.

After overhearing Duggee listening to a beautiful track by the Squirrel Valley Voices Choir, the Squirrels seek to learn more about the roles that make up a choir. A distressed Eugene then alerts them that half of the choir have been taken sick.

After hearing a strange sound, the Squirrels turn to Duggee to help identify its source. They learn about sound waves, and that it is possible to listen for different qualities in sounds, such as if it's loud, quiet, high or low.

The Squirrels see Duggee reading about wise animals and want to learn more about what it means to be wise.

Norrie is running late to Squirrel Club, so Duggee teaches the squirrels what a commute is: a journey that can take people from home to learn, work or play.
