aka ep150.5 Noni shows us a frog in a tank. Don mimes a frog, jumping, as he sings 'Mr Frog'. Noni follows the stages of development from tadpole to frog and does hand actions to the song, 'Der Glumph'. The clock shows two-thirty. Don tells and sings the story 'Caterpillars Only Crawl' while Noni does caterpillar crawls in a sleeping bag and turns into a butterfly with shower-curtain wings. Don plays a game, guessing what a caterpillar, tadpole, seed, maggot, wriggler and baby will become when they grow up. Noni shows pictures for the poem of the week 'Tomorrow I'll Be Five...', then sings 'Running to the Corner'. Through the windows we see a boy going to school. Don picks up the children's song, 'This is the Way'. Noni prepares Little Ted for school, with teacher Humpty and a class of toys. The presenters sing 'Clap Your Hands'.
