My kids (2 and 4) always quarrel killed tablet when they are allowed to play this game. All the animals in the forest and meadows make sounds. You can load the train with different things, must go build a bridge and show the train route. Just great! I find it just a shame that there is only this one from Lego Duplo are in the Amazon Android Store, although it would be many more free apps ... but so the children have to stop playing on the phone.
