When JoJo and Gran Gran visit the beach, JoJo is surprised to find the sea isn't there anymore! Gran Gran explains that the sea is there, but it's just further away as the tide it out, making it the perfect time to go beachcombing. Together, they see what interesting things they can find. JoJo learns all about fossils, as well as the people in the past who helped discover ones that are millions of years old, hidden within the beach. JoJo even finds a few special things of her own!

JoJo thinks she's seen every animal that visits Cynthia's garden. But Cynthia shows JoJo her new night-time camera, which can take photos of nocturnal animals JoJo has never seen. Gran Gran has a plan to help JoJo discover these night-time animals – they can leave a footprint tracker out overnight outside her house to find out which ones visit them. The next day, they check the tracker. As hoped, there are lots of prints: hedgehogs, foxes and more! Best of all, Cynthia gets some photographs of the night-time animals to share too.
