Megacity

When the boy and the dog are in the city starting the singing he had a smile but when he realised they hadn't made much money that made him sad. He really doesn't like the city because it is noisy and he wants to get closer to nature. The city is really loud. It appears he is also sad because it is night time. He wants a motorbike which appears to be on the poster. As the money grew he got happier.

When he got to the countryside he was happy but the realised he didn't need a bike because the countryside was all he needed. When he fed the dog he was happy.

And he had a nightmare on a trash can that made him sad.

In the countryside he is happy because it is quiet and more colourful than in the city.

And the system of how much times he is happy. The first one is a happy emoji, the next one is happy one and then a sad emoji for a day and a sad emoji when he had a nightmare. He was also happy when he saw the money go up and when he fetched the money with his dog.
