Now that the Minitwins know how to make themselves small and become big again, the ants warn them that Zappa the field mouse has got himself into trouble. Being so greedy, he has got too close to a trap and has fallen into it - he must be saved! All the animals get together to help him, but things will be more complicated than they seem and they will need extra help to get him out of trouble.
With full-colour illustrations, mixing comic and picture book, with short texts and capital letters, but above all, with a great sense of humour, Elisenda Roca brings us the adventures of these two twins in the animal world.
