The little dragon Cucumber is very upset, as today is a special day! Today he is going to school for the first time! On the way, he meets Oscar, a little gluttonous dragon, who unfortunately cannot go to school because his parents won’t let him. "What a shame," says Cucumber. "Very unfortunate," says Oscar. Because he really wants to learn to count, to write, and to read. Will the two little dragons manage to convince Oscar's parents that at school one learns a lot of useful things?
