My half of a trade by the awesome watergleam! I hope you like the colored version! I really enjoyed coloring the bubbles!
I am not sure if it is possible to blow bubbles under water, but we're gonna just suspend the laws of physics in the name of art. :P
Her half of the trade, which is far cooler than mine, can be found here! http://www.furaffinity.net/view/4797011/
