Fix and Foxi

F&F are provoked on their roller skates by a motorcyclist and enter a race. F&F wake up at night and believe they see an alien attacking Lupo. A contest between grandma Eusebia and uncle Fax to see which of the two is more vital and sporty. Mom has won a quiz and drags the whole family to the opera. They all have a lot of fun there - and make for a very unusual performance.
