Phaser Juicy not working!

[nicwhitts]

I'm trying to finish off a game by adding some effects, I want to 'jelly' some objects like in this game:

But it only seems to 'get bigger' and not return to its original size?

 

Any ideas?

grave = game.add.sprite(5, 2, 'grave');.....this.juicy.jelly(grave);

The screen flash and shake works fine.
