It is a simple and nice story, made by Seve Calleja, using the repetitive structure he has seen in many stories. this one. And as we are accustomed to the work of the Biscayan writer, we have received this version in Basque thanks to the translation of Xabier Monasterio.

Mr. Sator calls his nephew Satortxo on the phone for the young Satortxo to remember that it is his uncle's day. And as a result of this call, the nephew begins a trip to his uncle's house. The narration of this journey is the story of how Satortxo does not bring anything to his uncle (nothing occurs to him), but in the meantime he encourages all the friends he finds along his journey to his uncle’s party, which carries with him a wide variety of gifts.

That game is the basis of the book's argument, Satortxo meets the squirrel Ilegorri and the two friends launch on the road until they find Magu with the mouse. When all three of them get started with the mouse, they go to the bakery at Berritsu Satitsu in search of flour to make the dessert. And then they will be joined by the hedgehog, the beaver… and some friends, whom they invite, by the invitation of others: “Do you say you’re going to a party? Well, if you need me for something, I’m willing to help,” until I form a good crew: “‘One, two, three, four, …’ the bat is counting the guests in a low voice. "What a crowd! he thought to himself. The comrades have realized this and each one has started to show up.”

The narrator of this story is a third generalist who recounts the story in a chronological way. The structure of the book is also simple, structured in twenty short chapters of interviews that make reading easier. The colorful images of Carmen Aguirrezabal also help to follow the line of argument and to better understand the development of history.

The story, as the reader hopes, ends with a party at Mr Sator’s house: “Now everyone is there and everyone is eager to celebrate Don Sator’s birthday. And then, once all the food is eaten, the circumstances of the march will tell each other. And then they'll dance. And they'll talk about songs and laughter. They have all night to have a great time.”

Calleja is a simple and quick story, which has as its protagonist an extravagant group of animals. And as usual in some papers, the journey is more interesting than the goal. The feast of Mr. Sator is the goal, the story is the journey.
