JoJo and Gran Gran have fun finding Gran Gran's old clothes. When Charlene brings round a sewing machine, it's time for a Gran Gran plan – they can make JoJo some new clothes too!

JoJo and Gran Gran spot a bird's nest in Cynthia's garden, which inspires JoJo to make a nest for Panda. Cynthia and Gran Gran teach JoJo about all the nests that different birds make to help their babies. Gran Gran has a plan: while JoJo waits for the eggs they found to hatch, they can go to the park and see all the ducklings that have already hatched out and about! Meanwhile, Daddy helps teach JoJo how to whistle just like a bird. After lots of tries, JoJo is finally whistling away! Soon, back at Cynthia's, there's a lovely surprise - the eggs have hatched.

It's been raining, so JoJo wants to get outside and splash in the puddles. Isaiah arrives for his play date with JoJo, but Isaiah wants to stay inside and read his science books. Gran Gran suggests they compromise, but what is a compromise? Gran Gran has a plan: they can use the puddles outside to do a science experiment inside. They use timers and the sun to track the edge of the puddle and find out how long it takes for a puddle to disappear.
