Was ist bloss mit Gisbert los?

Gisbert has many friends and feels very comfortable in his giraffe skin. One day he hears two hyenas whispering about his brown spots behind his back - and feels how he suddenly gets smaller! Then the hippopotamus finds its trumpet playing terribly crooked. And again he shrinks a bit. After all, it feels so small that it even fits under the sofa. But when one day his friends present him with a piece of cake and a postcard, Gisbert finally knows what's wrong with him.
