'Pop' floating like a balloon

For one of my animations I want the word pop to float up into the centre of the screen for the 'O' to grow in size, then pop and then the 'P''s to float back down and lie at the bottom of the screen. I have been attempting to manipulate the sense of a balloon floating. This was my first attempt. It is a bit too fast and there are too many angles.

This is the second attempt which I am happier with. Though I will have to use create a layer for each letter so that the 'O' can increase in size on its own.
