JoJo has lots of questions about the bin lorries that keep Gran Gran’s street tidy. They go off to join the Nature Club and help Cynthia with a litter pick in the park. With gloves on and litter pickers at the ready, JoJo and her friends set off, collecting litter from around the community garden. But how will they know which recycling bins to use? There are so many to choose from. It’s time for a Gran Gran plan!
