This is a puzzle game like Sokoban, only when you press the 6 buttons in a certain sequence can you turn all the animals' face to you, then there is a song come out. If you press the wrong button, all the animals will turn back to you. After doing a lot of user tests, I found people would be really angry with it, because maybe one button will ruin your effort before. But at the same time, people were really excited about playing it, when they succeeded, they would feel very happy.

I don't give any clue of how to press the buttons, just let users to deduce and try, I think this is the most interesting part of puzzle games.
