Because det positive reviews we got the app. But somehow it eludes my understanding. Only a pupsender elephant and then individual animals with instruments. No story, this will probably leave entirely to the imagination. The sound does not convince me and the drawings are not really my thing. The enthusiasm of the child keeps in limits. At least the individual instruments are designated and alluded. Maybe yes you have the books to know ... My conclusion: you do not necessarily have. If for nothing and therefore okay.
