One day Mommy, Daddy and the kittens go for a walk in the park. They arrive at their favourite spot but the beautiful trees have been replaced with a new gazebo. They learn the trees were knocked down by a strong wind. Cookie finds acorns on the ground and asks his parents what they are. Mommy tells the kittens that if they plant an acorn in the ground, it will sprout and later turn into a big oak tree! The kittens are delighted and immediately want to plant a lot of trees to make their favorite clearing look like before. The kittens return home and plant various seeds in pots, but the trees are taking a very long time to grow.
