Surprise button: Tutorial Six

When you click sprite2, which is the carpet, it changes colour by the quantity of 25, colours are sorted by numbers so as the quantity is 25, the change of colour is going to be more noticable that something with the quantity of 2.
Then once the colour has changed a random picked drum sound will play for 0.2 beats. Once again there would be a change of colour after a sound is played. This process has no repetition so it would only start again when you click the carpet again.
