Re: bubbles to flowers

I'd try playing with CC Particle World. The "Textured disc and Textured Square" particle options let you assign a custom image to the particles. You could then make a very wide particle emitter and put it below your screen shooting upwards. Turn off gravity so you have no change in velocity. You'll have to spend awhile playing with the physics and animation properties to get things to move how you want, and I doubt you can get an exact match for the movement of CC bubble, but you can probably come close.
