Fix and Foxi

Uncle Fax has a toothache, but he won't go to the doctor. The friends ride their bikes and Lupo ends up in a cave. A stone age man finds the children. The cinema owner is ill, the small children are unhappy. The four friends want to help. In the middle of the night mum hears some noises and sends the not so brave men of the house to look for them. A rumbling surprise awaits them.
