Minor: changes to speaker and birds metaphors

Speaker Metaphor

There's now going to be two robots side by side. One orange and one purple to fit in with the colour theme. They both start off just moving around normally and playing music from their speakers. The purple robot then starts smoking and sparking etc. and shutting down and the orange robot has sound waves and musical notes coming from it and carrying on playing music.

Birds Metaphor

The changes made to this metaphor is that when the hawk flies over the birds, now all the birds are going to fly away, including an orange bird. Then two birds, a purple one and a normal coloured one flies in and perches on the bird bath.
