A little mouse who is fed up with her bad life in winter wishes to be a kitten. The magic lantern grants her wish. As soon as she becomes a cat, she is chased by a dog and finally snatched by the strongest cat in the neighborhood. The cat keeps scenting the mouse, but can't figure out her secret. Only when the mouse cat's friends try to save her does the situation become frightening.
Two children, a boy and a girl, are each given a piggy bank. The boy is unimpressed and happily continues to spend his money. The girl takes every opportunity to "feed" her beautiful pig quite often. She is rewarded for this exemplary behavior with a ride to toyland.
The sun is drunk! She has emptied every beer barrel! Instead of going down, she has forgotten about time and is messing up the whole city. Will they have to cancel the lantern festival for the kids? Little Max, Tüte, the director of the observatory and the head of the fire brigade all try to catch the sun so they can take her to bed. Hopefully they can save the party for the kids.
