Change Icons

We like the Iconmoon icon set. However, it is a little more techie oriented than what a beach themed community website needs. We would like to add a few icons that better reflect the links. We like the way when we use the paw icon, it is blue but when you mouse over it turns white inside of a solid blue circle. We have uploaded icons to override an Icomoon icon but when we do, it is static. We need it to animate like they do in Highend.
