Die Sendung mit der Maus

• The mouse is orange with brown ears, arms and legs. In order to solve problems it can stretch its legs as long as it wants, jump a rope with its detachable tail or fetch tools from its body.
• The elephant is blue with yellow toenails and is smaller than the mouse. It can be characterized as curious, very strong, spontaneous and faithful. When it appears on the stage it trumpets loudly. It likes to sleep, or to laugh when the mouse has done something wrong. It appears in many of the Mouse-Spots.
• The duck is yellow (with orange beak and feet), smaller than the mouse but larger than the elephant, so that their relative sizes are exactly the opposite of those of their real-life counterparts. The duck is naughty and quacks loudly, "chaos comes onto the stage" anytime it appears. It appears in the mouse-spots less frequently than the elephant.

The mouse, mascot of the show

The show starts with its theme music,[16] unchanged since 1971[9] and recognised throughout the German population.[17] The introduction consists of a few bars of the theme and a German voice-over describing the topics in that week's show. The voice-over is then repeated in a foreign language.[9] Initially, Turkish, Spanish and Italian were used, in order to include the children of foreign guest workers (Gastarbeiter),[18] but now, other languages are used as well. The foreign language changes every week.[3] After the theme music ends, the foreign language is identified.

Between the show's segments are "mouse spots", hand-drawn cartoons of 30 to 100 seconds that feature the orange mouse and its friends, a small blue elephant and a yellow duck. None of the characters speak.[19] Rather, sound effects and music comprise the soundtrack as the characters interact and solve problems. The animated interludes serve to separate the segments, offering young viewers a moment to relax, avoiding sensory overload from too rapid a succession of input.[9]

The idea for the educational film shorts came from one of the founders of the series, who noticed that children were very aware of the advertising on television. They were very well-made with very good photography and he got the idea to make "commercials" about reality. The first production answered the question, "Where do bread rolls come from?"[4] Some 400 letters a week arrive at the production office, and a large part of each show is used for such features, often answering questions asked by viewers.[3][4][20] Segments have covered such topics as:

• How re-usable hand warmers work[21]
• How the Internet works[22]
• How a hot-air balloon flies
• How to make electricity from lemons, enough to light a light bulb[23][24]
• How a cell phone works[25]
• How solar cells work[26]

Lufthansa Airbus A321-100 D-AIRY “Flensburg” with the Mouse

A stuffed toy "Mouse" flew into outer space and was a "guest" on board the Russian Mir space station, where it appeared in an educational segment. The stuffed toy was later brought back to the producers on earth.[27]

A number of the educational segments have also dealt with difficult topics, such as life in Germany in the aftermath of World War II,[17] the Chernobyl nuclear disaster[5][28] and death.[3][29] Care is taken to explain things in a way that is comprehensible to young children.[30] Analogies are used to explain concepts,[17] and often everyday items already known to most children are used to illustrate. For example, a segment on the Battle of the Teutoburg Forest was produced using Playmobil figures to represent the three Roman legions involved, a total of 16,500 soldiers. Wanting to convey how large a force that was, the program purchased 16,500 Playmobil toy figures and dressed them up as Roman soldiers, lining them up into columns as they would have appeared in real life. The columns of toy soldiers took up 200 meters.[31][32] These toy Roman legions are now housed in three museums in different parts of Germany.[32]

A segment on the internet shows messengers running through the hallways of a large building, delivering messages in envelopes (data packets) from the user to servers and back. The hallways represent the data lines and the offices were internet hosts. In just eight minutes, the program accurately describes how the internet functions in a manner simple enough for children to understand.[22] In the case of industrially produced things, each step is shown in great detail, so one can actually see how, for example, a piece of metal is formed by a tool. If something happens too fast for the naked eye it is shown filmed in slow motion. After each step, usually the previous steps including the new one are recapped briefly to help children remember what they already saw. Concepts which are not visible at all are explained with some form of analogous portrayal.[30]

Accordingly, the language used in the narration is kept very simple.[9] The segments are usually narrated by an off-camera voice. Sentences are short.[33] "Big words" are not used, and difficult concepts are broken down and described while they are being shown on camera.[34] This is designed to free children from the more abstract concepts and devices of language, thus giving their minds space to comprehend the concepts explained rather than having to struggle comprehending the language of the explanation. Nonetheless, the educational film shorts are such effective presentations of their subject matter, a number of them are used as teaching tools at universities and colleges.[17][18]

Every show also has at least one cartoon. Some are old classics, like the adventures of Zdeněk Miler's Mole[16] or newer cartoons, like Charlie and Lola.

As the last part of every show, Käpt'n Blaubär (Captain Bluebear) tells his pink, green, and yellow grandchildren a cock-and-bull story, which his grandchildren always doubt to be true. His sailor side-kick, Hein Blöd (Hein Stupid), a rat, was created as a buffoon, a device that allows freedom for his character to express things other characters cannot.[35] The characters of Käpt'n Blaubär, his grandchildren, and Hein Blöd were created by Walter Moers and made popular by Moers' book, The 13+1⁄2 Lives of Captain Bluebear and Blaubär's appearance on Die Sendung mit der Maus. Käpt'n Blaubär is voiced by veteran German actor Wolfgang Völz,[36] with deep timbre and an accent[37] of the Low German common in coastal area of Germany.[10] The scenes on board Blaubär's ship are made with Muppets-style puppets, while his stories are short animated films.

Käpt'n Blaubär is sometimes replaced or complemented by the stop-action animation, Shaun the Sheep ("Shaun das Schaf"),[9] and one episode of The Mouse featured a visit to Aardman Animations, showing how Shaun is produced.[38] This educational film short, broken up into segments because of its complexity and length, showed the various stages of production and the amount of work required to create a single episode of Shaun.[39] The episode of Shaun seen in production was then broadcast in its finished state at the end of that Mouse.

One episode featured a little crocodile named Schnappi (Snappy) singing about his life in Egypt on the Nile. The song went viral in Germany and became a hit in other countries as well.
