Yakka Dee! celebrates children communicating - because talking fills you up with whizz, pop, bang! In this episode, Dee encourages a friend to say 'bike', and we go on a whirlwind word adventure. We see lots of different bikes doing lots of different things. There's a hopping bike, a shopping bike and even a dinosaur riding a bike! Dee has a new green and shiny bike and we see her going for a bike ride with loads of friends. The journey is repeated with some special surprises along the way and everyone has a boogie when Dee's friend finally succeeds in saying today's word.
