It's bath time, but Orbit the space dog is far too busy digging for bones in the garden and Tuna the star cat is nowhere to be seen! When Astro and Luna finally get them into the bath, Tuna gets soap in her eyes and Orbit gets water everywhere! Next, it's time to have their fur brushed, but there are lots of tangles and it hurts. And Orbit and Tuna both think brushing their teeth is really boring. At last Orbit and Tuna are tucked up in bed ready for their bedtime story, but poor Astro and Luna are exhausted. Something has to be done! Luckily, with the help of some gold star stickers and special reward charts, Orbit and Tuna are soon enjoying bath times.
