Okay well I am a little dumb, stuck on this for while, and I need a little help. So here we go:
Homer notices that his shower is covered in a strange green slime. His friend Barney tells him that coconut juice will get rid of the green slime. Homer decides to check this out by sprayinghalf of the shower with coconut juice.He sprays the other half of the shower with water. After days there is no change.

So now the questions are:
