Professor builds Princess a robot, which becomes her new favourite toy, but she soon comes to realise there are some things a robot cannot do that a teddy can.
Princess is thrilled that everyone is going to help her build a seesaw, until she finds out they are all too busy doing other things. It is up to Princess to teach them that breaking seesaw promises is not very fair.
Princess decides to become a cowgirl just like Tilly the Kid, a character from her favourite series of books. But being a cowgirl is tougher than she expected, and soon she finds herself wondering if being a princess instead isn't so bad?
The royal household have a new pet, a little fish called Fishface. With Algie's help, Princess learns how to look after him, but she's not convinced that Fishface is happy in his new home. How will she help him settle in?
