JoJo and Gran Gran are having a sleepover. JoJo loves her Captain Chloe dot to dot of the night sky and the treasure chest constellation that she’s found. The constellation gives Gran Gran an idea – they can have a sleepover plan to go stargazing in the garden. What can they spot in the night sky? Are there more constellations to find? And can Great-Gran Gran see the same stars in the sky?
