Sensory Build It

I like many of the other sensory house apps but this one is absolutely bizarre /completely random/has no cohesion to what is being displayed. There is definitely not much “building” going on here. I thought it would reveal parts of something little by little - like you tap the screen and a face shows, then tap again and eyes show, then tap again and a nose and mouth show. Or maybe you tap the screen to build a sandwich or a set of trains one by one, until there is a line of trains. The most this does is show a shadow of an object, and then show the full object. Also, in some of the scenes multiple animals will come out on the screen- one and then two and then one animal will stay the same while another animal will come out - but the animals have nothing to do with each other. Like a snake and a pig??!?! What exactly is this teaching someone, developmentally?
