Hiccups

Doodoowah has stuffed himself with blackberries, and now he has hiccups. It ruins their rehearsal: you can't play music with someone who's got hiccups. The others try to get rid of them, but it's no use. It seems their only option is to ask him not to practice with them. But Jasmine feels sorry for him. She discovers that Doodoowah's hiccups are tuned to a perfect A, and that's how they work out how to include Doodoowah in the rehearsal.
