Join Henrietta the Hippo, Gigi the Giraffe, and Tommy the Toucan as they embark on another playground adventure. This is the third in the series of the much-loved characters from Henrietta's World. Via the magical hopscotch this time, they have an adventure in space on the planet Zaytooloo. Henrietta, friends, and inhabitants of the planet Zaytooloo, the Watsels, help interesting characters to learn all about recycling, reducing, and repurposing waste. Read how they help the Litterbug Twins to sort out their rubbish into different types of recycling and help Tilly the Time Traveller to reuse items and give them a new purpose (upcycling).
