S1, E19: Dan the panda surprises Wissper with a problem she just wasn’t expecting: Dan wants to sing! For a big bear, Dan has a bit of a high squeaky voice. When he sings it does not sound very tuneful! Wissper needs help, so she summons Otis the oxpecker bird and Gertie the giraffe. They can’t change Dan’s voice so they teach him to harmonise and make the best use of his panda voice.
