animated bubbles in my health bar?

so i have this awesome health bar now,

but i was wondering how/if i can add animated bubbles floating up the health bar?

You could add in a texture with bubbles (tiled) and use a panner node for the uv to make them go up (you could use a sine node to make them go slightly left and right) and mix on top of the color (maybe with an add or multiply node) before the mask node.
