I have seen the movie several times. In fact this is meant as a mini series. It is one of the first blue screen puppet movies as far as i know. Surely you can see that the environment doesn't fit in exactly but this also has a charme on his own. Remember, these were the early 70's !!!
Story: It is about a 9 y/o boy (3rd class) who is visited by surprise late in the evening by a robot which is also in the 3rd robot class of his robot school. The robot "ROBBI" asks "TOBBI" to help him with his school examination. He has been given 3 difficult questions to ask like "Who is standing at the north pole and starts with the letter P" (if i remember well). ROBBI the little robot can do a lot of tricks. So he is able to stretch his arm to 10 foot length for example. TOBBI is an inventor so he designed the "FLIEWATÜÜT" which is a German combination for a multi purpose vehicle which can FLIE (FLY) , ship on the water (WA) and drive on the road (TÜÜT=BEEP). The FLIWATÜÜT rans on raspberry juice or alternatively on cod-liver oil. As TOBBI calms down and ROBBI explains and asks for help, they become friends soon and starting an incredible adventure through Europe.
Nice characters (a sweet little mice, a helpful dolphin) and suspense (the black castle) everything is in the right place here. You or your kids will learn from this movie that friendship solves almost any problem.
Highly recommended to all of you who are open minded to puppet movies with an educational message. If you are not common to German language, you could at least admire the set which was very sophisticated for 1972.
