Think of Oyster and the first thing which comes to our mind is 'Pearl'. We all know that the Oyster lives in a shell.

When any irritation gets into its shell, the oyster first tries to take it out. But when it can't, it uses the same irritations to create one of the most beautiful things in the world.

It uses the irritations to do the best thing it can if given a chance. Yes it makes a Pearl.
