The Octopus!

One day, the kittens go to a water park with their parents. There they meet Mustard who is going down the slide with her favorite toy - the Octopus. When Candy sees the cute little Octopus, she asks Mustard to borrow it for a while, so that Candy can play with it for some time. Candy takes the Octopus everywhere she goes and doesn't notice when she loses track of it. Mustard comes to take her toy back and it turns out that nobody knows where the Octopus is. Cookie, Candy, Pudding and Mustard begin to search for it. They visit all the places where Candy has been before and find the Octopus! The kittens learn to use logic to help them find things that they lost and to be extra careful when you borrow your friend's toys.
